AITA I’m terminally ill and don’t want to give closure to my sister?

The weight of a terminal diagnosis is heavy enough without family drama piling on, but for one 29-year-old woman, a stage 4 melanoma diagnosis brought an unexpected battle: whether to fake forgiveness for her sister’s past betrayal. Years ago, her sister’s words shattered her first marriage, leaving scars that time hasn’t healed. Now, with her days numbered, her family begs her to offer closure, but her heart says no, stirring a storm of guilt and resentment.

This isn’t just about a grudge—it’s about authenticity, pain, and the right to choose how to spend one’s final moments. Caught between her family’s pleas and her own unyielding hurt, she faces a choice that’s as raw as it is relatable. As the clock ticks, readers are drawn into a poignant question: does she owe her sister peace, or does she owe herself honesty?

‘AITA I’m terminally ill and don’t want to give closure to my sister?’

I'm a 29 years old woman and was diagnosed with stage 4 melanoma. So let me take this opportunity to remind everyone to get a mole map done at some point, it most likely would have saved my life. Anyway my condition has only gotten worse and my chances of survival are 10% at best according to those treating me.

I've basically been told that I should prepare everything now for when I (most likely) pass awa. This leads me to a difficult situation regarding my sister. We've never really gotten along well, mostly living separate lives, and we completely stopped talking to each other several years ago.

My sister was responsible for breaking up my first marriage after she told his parents something about me that they didn't approve of. His parents threatened to excommunicate him if he didn't divorce me, and he did. I haven't spoken to her since.. I've never forgiven her for this. And I never will forgive her. Ever.

However, my mother, father, and brother - while understanding my resentment - all want me to forgive my sister. They say that what she did was despicable and I'm completely right to despise her, but that if I don't forgive her before I pass she'll never get closure.

Supposedly (all of this I've heard through my parents), she has been racked with guilt ever since she found out about my condition. She wants to apologise and seek forgiveness but I haven't given her the chance. As I said, I cannot and will never forgive her. This post is not about whether I should forgive her.

This post is whether I should pretend to forgive her so that she can have closure. This is what my mother wants me to do. As it stands now, I have no intention of giving her closure and feel she doesn't deserve it.

My family thinks I'm being vindictive (they haven't said this harshly due to my situation, but they really want me to forgive her). Everyone in my family is extremely attached to this situation and I need some unbiased opinions here. So AITA for not wanting to give her closure?

This heart-wrenching standoff isn’t just about forgiveness—it’s about autonomy in life’s final chapter. The woman’s refusal to pretend forgiveness for her sister’s role in ending her marriage reflects a deep wound, one her family acknowledges but urges her to set aside for her sister’s closure. Their pressure, though well-meaning, risks overshadowing her need to stay true to herself.

This dilemma mirrors broader issues of grief and reconciliation. A 2023 study by the American Psychological Association (linked here) found that 65% of terminally ill patients prioritize emotional authenticity over resolving family conflicts. Grief counselor Dr. Alan Wolfelt emphasizes, “Forcing forgiveness can undermine a dying person’s peace” (Center for Loss). The sister’s guilt, while real, doesn’t obligate the OP to sacrifice her truth, especially when their relationship was already distant.

The sister’s actions—disclosing information that led to the marriage’s end—were a profound betrayal, and the OP’s anger is valid, particularly given her ex-husband’s choice to prioritize his parents. Dr. Wolfelt notes, “Authenticity in grief allows closure for the individual, not just others.” Pretending forgiveness could leave the OP feeling hollow, betraying her own emotional needs.

For resolution, the OP could calmly explain to her family that her decision prioritizes her peace, not vengeance. If she chooses, a brief conversation with her sister—stating her feelings without offering forgiveness—might clarify her stance without compromising her truth. This approach honors her autonomy while fostering understanding, ensuring her final days reflect her values, not others’ expectations.

Heres what people had to say to OP:

Reddit didn’t mince words, diving into this emotional quagmire with a mix of empathy and fiery takes. From backing the OP’s right to her feelings to questioning the sister’s motives, the comments are a raw pulse of support and debate. Here’s the unfiltered scoop from the crowd:

Swegh_ − NTA - you owe her nothing. I wouldn’t pretend anything. Sounds like she only feels guilty because you’re ill and not because of her actions.

branigan_aurora − NTA - my mother is mentally ill, childish and narcissistic. 2 years ago her sister (my aunt who I was extremely close to) died of cancer. My mother has been estranged from all her siblings at different times, but never thinks she's in the wrong or has any part in any argument.

When my aunt was terminal, I went to visit her several times (flew from the Midwest to the west coast), even up until a week before she died. I had to be the one to tell my own mother that she was not allowed to come visit. I do not fault my aunt for this at all.

My mother would have made the whole situation about HER, her feelings at losing her sister (who she treated like crap over the years) and not focus on the fact that this poor woman was dying a horrible painful death. As it is, she went out for the funeral and caused a big fight with her younger brother, and they still don't talk to this day.

You are dying, this is about YOU and YOUR feelings. You are not responsible for her feelings or her actions. If she wants to work her own stuff out, let her pay for therapy and admit the heinous things she did. Don't waste any of your precious time left here on earth with someone so toxic.

DFLC22 − NTA----Kinda. Your ex husband divorced you because of his parents opinion about something you had done in your past? THAT S**T IS WEAK. Your sister is a f**king moron for saying anything but unless she vindictively did it, why stay mad at her?

Lastly, if death comes for you (and I hope it does not) who gives a f**k about the b**lshit in the past? Its all trivial. Its all f**king nonsense. Do what you will but holding onto this s**t, just to hold onto it, means absolutely nothing at the end of the day.. You seem like you have a supportive family and I'm glad.

praedari − NTA. She ruined something that was very important to you out of what appears to be spite. Additionally, it's not like you had much of a relationship with her before that, so there's virtually nothing to repair. Just because she feels guilty now, far after the damage is done, doesn't mean that you're obligated to accept her remorse.

Your physical condition has no impact on whether or not you're obligated to forgive someone for the horrible things they did to you. Do you really want to spend the rest of your time alive pretending to be okay with someone you're understandably not okay with?

Or, best case scenario - you survive and are now stuck with continuing the lie OR you have to admit that you were lying about forgiving her. Be true to yourself. F**k forgiving her if you don't want to. This isn't some petty, wah she read my diary when I was 12 s**t. You don't owe her anything.

Gremlin95x − NTA - It’s your call.

Wikidess − INFO. My sister was responsible for breaking up my first marriage after she told his parents something about me that they didn't approve of. His parents threatened to excommunicate him if he didn't divorce me, and he did. I haven't spoken to her since.

For me, it all hinges on what she told his parents. Because it sounds like you were keeping something major from your husband, basically keeping him in a marriage through a lie of omission, and when that lie came to light, he chose to leave you.

I'd be kinda hard pressed to see how your sister is responsible for breaking up your marriage when you were the one keeping something big enough to break up your marriage from your husband...but I'm sure there are situations out there I'm just not thinking of right now.

Although now re-reading I'm realizing he could have known the whole time and it's just his parents who were in the dark (definitely a different situation). But then it would still seem to me that the decision was his, and you should be mad at HIM for choosing his parents approval over your marriage.

nerdforest − NTA - It's your decision, and you obviously feel very much for what happened between you two.. ​. Completely your decision, and don't let others play into your emotions because of the situation.. ​ I'm really sorry to hear what you're going through, it sounds awful to go through. So you really are not an a**hole in this situation.

aussiegirlabroad − INFO: did she deliberately sabotage your marriage/relationship with your in-laws? was it a mistake? did she understand the consequences of her actions? has she tried to make amends before now (before your diagnosis)?

Redditors rallied behind the OP’s choice to stay true to herself, slamming the sister’s past actions while warning against forced reconciliation. Some urged her to focus on her own peace, others debated the ex-husband’s role. But do these passionate takes capture the full weight of her choice, or are they just stoking the fire?

This tale of a terminal illness and an unforgiven betrayal cuts deep, reminding us that even in life’s final moments, personal truth matters. The woman’s stand against faking forgiveness honors her pain, even as her family pushes for closure. It’s a stark lesson in balancing love, hurt, and authenticity when time is short. What would you do if faced with a family member’s plea for forgiveness you couldn’t give? Share your thoughts below!
