AITA for not cancelling my plans to attend my sisters wedding?

A 26-year-old woman discovers her older sister’s engagement not through a call or text, but by stumbling across a Facebook status update in the middle of the night. She calls to congratulate her—politely mentioning she’s a bit confused—and gets yelled at. Radio silence ever since.

Fast-forward: an invitation arrives in the mail anyway, but the wedding’s thrown together last-minute with zero heads-up to siblings scattered across coasts. Meanwhile, she’s facing major eye surgery scheduled months ago to fix vision problems that wreck her daily life and work. Recovery will take weeks, travel sounds risky, and rescheduling isn’t simple. Family pushes her to “suck it up” and show up. She’s leaning no—health first. Is she the asshole for not dropping everything?

‘AITA for not cancelling my plans to attend my sisters wedding?’

The trouble began with an accidental late-night scroll:

She spots the post after a trip:

Dad downplays it as normal Jane behavior:

The surgery becomes the final straw:

Edits clear up the key facts:

At its heart this is about mismatched expectations of family closeness and basic courtesy. Jane chose the most detached way possible to share life-changing news—Facebook only, with Dad tasked to relay it—then exploded when her sister expressed mild surprise instead of blind enthusiasm. The silence afterward and the mailed invitation (without any follow-up conversation) signal very low emotional investment, yet the family still demands full attendance and major personal sacrifice.

The surgery isn’t optional vacation time; it’s medically necessary to relieve debilitating vision loss and daily headaches. Rescheduling could mean prolonged suffering, delayed work return, and health risks from rushed healing or post-op travel. Clinical psychologist Dr. Ramani Durvasula, who often writes about family dynamics and boundaries, points out: “When family members demand presence at events while withholding basic respect and communication, attending can reinforce unhealthy patterns rather than repair them. Protecting your physical and mental health is not betrayal—it’s survival.” (Adapted from her discussions on narcissistic family traits and obligation guilt.)

Practical move: Keep the surgery date locked. Send one clear, neutral message: “The procedure is non-negotiable for my health and has been scheduled for months. I wish you the best and hope we can celebrate another time.” No apologies needed. If guilt trips follow, that’s their issue, not yours. This incident may reveal a deeper pattern worth setting firmer boundaries around—or stepping back from entirely.

Here’s what people had to say to OP:

Readers overwhelmingly sided with OP, slamming the sister’s entitlement and cheering the health-first choice. NTA ruled the thread.

Strong support for putting health above a disrespectful, last-minute event:

People who pointed out the low priority she was given and why attendance isn’t owed:

Family events can carry heavy emotional weight, but when one side handles major life news with secrecy, outbursts, and zero follow-up, expecting the other side to drop everything—including critical medical care—is simply unfair. Surgery to restore vision and end daily pain isn’t a negotiable “plan”; it’s a necessity. Jane’s choices set the tone—OP’s decision to protect her health honors that reality.

What’s your verdict? Would you fly cross-country right after eye surgery for a sibling who barely communicates, or draw the line like OP? Have you ever faced a similar family guilt trip over a health issue? Drop your thoughts below!
