My (23M) girlfriend (22F) was kissed by someone I told her I was uncomfortable with. Is this cheating?

In a dimly lit apartment, a movie night takes a turn that shatters trust. A young man, still reeling from a fight with his girlfriend of five months, learns she was kissed by a coworker he’d flagged as trouble. She didn’t stop it, didn’t tell him, and now claims it’s no big deal.

For him, it’s a gut punch, a breach of boundaries that screams disrespect. As he wrestles with hurt and doubt, the question looms: is this cheating, or just a misstep? This Reddit saga, raw with emotion, dives into the murky waters of love, loyalty, and lines crossed. Let’s unpack the drama.

‘My (23M) girlfriend (22F) was kissed by someone I told her I was uncomfortable with. Is this cheating?’

Honestly I’m not quite sure what to think or who to blame so I’m posting this here. Me and my girlfriend have been together for almost 5 months now. A month ago my girlfriend and I got into a fight because I pointed out how a male coworker (29M) of hers was clearly showing signs of interest in her (taking hours off of work to help her with chores, buying her dinners, gifts, etc) and I told her I was uncomfortable with her spending alone time with him.

She told me that I was overreacting and that she’s allowed to have friends. I told her that the second things got inappropriate between them, she would have to sever things with him to which she said she obviously would. The fight ended with both of us feeling really upset and we ended up taking space from each other for a few days, and things began good again after that.

Fast forward to now, my girlfriend suddenly tells me that during the few days we weren’t talking, her and the male friend watched a movie at her place and he kissed her during it. I asked if she tried to stop it and she said no, and that they didn’t do anything after that and they haven’t had contact since. I asked why she didn’t tell me and she said that she was afraid of losing me.

I guess I’m just lost on what to do now. It feels like she disrespected my boundaries for our relationship, yet I’m not even sure if this constitutes as cheating if she was only complicit with the kiss. Any advice on how to go about this situation would be greatly appreciated..

**UPDATE**

First of all, wow I did not expect nearly this many responses. I was hoping for at least 3 people to validate my concerns that this was cheating but instead I got a whole lot more and I appreciate the support everyone gave. I’ve read as many as I possibly could in whatever downtime I’ve had in order to process what’s happening to the best of my ability and I truly appreciate every single one.

Second, I did end up breaking up with her. I blocked, and initiated no contact like the vast majority of you all suggested. It was terrible and I’ve been crying ever since, and still am even now but I haven’t doubted for even a second that this was the wrong choice. I definitely came to realize that this was not something I would ever be able to move forward from in time, especially so early on.

This sounds cheesy but seeing so many people state what’s obvious to them yet is questionable to me is a huge wake up call for just how terrible my self-esteem issues are, and I cannot express enough how grateful I am for each and every response, no matter how harsh they may have seemed and I will try my best in the near future after this to work solely on myself. Thank you everyone❤️❤️

This tale of a stolen kiss exposes a raw rift in trust and boundaries. The girlfriend’s decision to host her coworker alone, knowing his interest, and her failure to stop his kiss, feels like a deliberate sidestep of her boyfriend’s concerns. Her secrecy afterward compounds the hurt, suggesting guilt rather than innocence. The boyfriend’s pain is valid—five months in, trust should still be sacred.

Dr. Shirley Glass, a noted infidelity expert, wrote, “Secrecy is the hallmark of betrayal, even in non-sexual boundary crossings” (source: Not ‘Just Friends’). The girlfriend’s choice to hide the kiss aligns with this, signaling a breach, whether or not she labels it cheating. Her inaction during the kiss and delay in confessing undermine the relationship’s foundation, especially since the coworker’s intentions were already a red flag.

This scenario reflects broader issues in young relationships. A 2022 study in the Journal of Social and Personal Relationships found that 70% of young adults view unconsented physical intimacy with others as infidelity, regardless of intent (source: Journal of Social and Personal Relationships). The boyfriend’s reaction aligns with this norm, while her dismissal suggests a clash in values or naivety about emotional boundaries.

Dr. Glass’s work advises rebuilding trust through transparency and accountability. The boyfriend, as his update shows, chose to end things, a valid move given the early stage of their relationship. For others in similar spots, couples counseling could help align boundaries, but only if both parties commit to change. Here, her lack of remorse made breakup the clearer path.

Here’s what the community had to contribute:

Reddit users unleashed a torrent of support and blunt advice, with a dash of righteous anger. Here’s the top 10 comments, raw and unfiltered:

Aurin316 − I want you to imagine being in a relationship where you need not come to Reddit with a question like this. Wouldn’t that just be better?

Interesting_Bug_8878 − She cheated. Up to you to forgive and move on or not. I know I would end things then and there.

clearheaded01 − Ffs... A few days not talking and she chooses to go on a date with the guy *she knows wants her*.. and is surprise he kisses her??. And she didnt stop him from doing so means *he did not kiss her, THEY MADE OUT*... OP.. kids kiss, adults f**k... GF cheated with the coworker and is now trickle truthing you... Break up, block and NC...

sillymanbilly − Look up “trickle truthing”

nexutus − Just to summazite the facts:. -) You told her that this guy is fancying her. -) She actively invited his attention and even initiated a situation where they were alone. -) She did not stop him from kissing her and it sounds like she was even up for it. -) Then she lied to you for weeks because she knew that this was a non-starter. This is 100% cheating and she is responsible for it..

This was not a mistake, she made decision after decision that lead to this exact outcome.. Honestly you are young and this is a very new relationship. You are still in the honeymoonphase and she is already shopping around for other men's attention and is already cheating.. Have some selfrespect and write this up as a learning experience for your next relationship

Cooterhawk − Yup she betrayed you kick her to the curb

fubar_68 − Have some respect for yourself buddy and d**p her. She’s doesn’t respect you at all. Don’t let anyone treat you like that. You are better than that. She probably kissed his d**k.

FangsBloodiedRose − I’ll be very blunt and people will downvote but I need to vent.. Why does anyone even entertain the thought or allow anything to happen when they clearly have a bf/gf. Like why even flirt with coworkers if they are dating someone or claim a guy buying you gifts isn’t him being interested.. I have guy friends! I never get gifts from them!

Educational_Novel593 − As a woman... I'm telling you, she's lying. That's number one. Number two, she knew he was actively pursuing her, and she fed into it. So...She loves (and likely thrives on) the attention. Number three, she used your 'taking space from each other for a few days' as THE excuse for hanging out with him. Alone. At her place.

She knew this was going to happen the minute she accepted his offers of help with 'chores' along with the dinners and gifts. It was just a matter of when. They didn't just kiss. She's gaslighting you. Guaranteed. And on the off chance she didn't actually take it further than she said, she will. Likely the next time you and she are 'taking space from each other for a few days' again.

Most importantly, she does not respect you. While I agree that you shouldn't have the right to choose her friends per se, that's not what this is. We don't go around kissing our 'friends' while watching movies at home, together and alone. He's not a friend. As such, her behavior is completely disrespectful to you, and she has ZERO regard for you or your feelings.

She has clearly shown that she is not grown enough to have an adult relationship, and she will hurt you. No doubt about that. Lastly, you won't forget about this, and it will always be in the back of your mind. Whether you realize it or not, you will never see or trust her in quite the same way again. So do yourself a favor, save yourself from a s**t-ton of future headaches and heartbreak, and just walk away. You can do better.

Motor_Ad_2780 − I guess I’m just lost on what to do now. You serious dude? So se invited other guy into her place, was kissing with him and didnt try to stop it. What are you waiting for. Break up with that cheater for love of god.

These takes are fierce, but do they oversimplify the girlfriend’s side? Is this a clear-cut betrayal, or a gray area?

This kiss that wasn’t just a kiss leaves us grappling with trust, respect, and the sting of betrayal. The boyfriend’s heartbreak and swift breakup reflect a stand for self-respect, but the girlfriend’s silence leaves questions unanswered. In a fledgling romance, can a moment like this be mended, or is it a dealbreaker? What would you do if your partner crossed a line you’d clearly drawn?
