It can be incredibly difficult to deal with someone crushing on your partner, particularly if they don't seem to respect the boundaries of your relationship. On one hand, if you insert yourself in the dynamic it is easy to appear controlling or jealous. On the contrary, sitting back while someone tries to steal your boo isn't the ideal either.

This is even harder when the third party is aware their feelings are unrequited, and they seem to get a rise out of making everyone uncomfortable. While this happens across gender and sexuality, there is a trend of straight women hitting on gay men and thinking it's harmless when really it's disrespectful.

In a recent post on the Am I The A*shole subreddit, a man asked if he's wrong for wanting to cut off a classmate who incessantly flirts with his boyfriend.

AITA for not wanting to hang out with a girl because she's into my boyfriend?

OP shared that him and his boyfriend Mark have been part of a student's club for years, and just two months ago a woman named Jessica joined.

From the very start, Jessica made it clear she was attracted to Mark, and Mark was relatively avoidant and uncomfortable.

Jessica is the girl, my boyfriend Mark and I are both guys. We're all members of a student's club and while Mark and I have been members for a couple of years, Jessica joined about 2 months ago. As soon as she joined, she started drooling all over Mark and he was too embarrassed to tell her he's gay so he just spent most of the time avoiding her.

When OP eventually made it clear he was Mark's boyfriend during a recent round of drinks, Jessica laughed and gushed about how hard she'd been crushing on Mark.

I thought it was ridiculous, so when 10ish of us went out for drinks recently, we made it clear that we're a couple. We behaved as we usually do since all of our friends from the club know we're together, and Jessica saw it and she was like ohhhhhh you guys are a coupleeee! And we confirmed, but then Jessica, who I guess is a bit weird, started laughing and said: oh my god, that's so embarrassing, I totally have a crush on you, Mark!

Unfortunately, finding out the two are a couple hasn't changed Jessica's behavior, and now she's almost more incessant about finding out if she'd ever have "a chance."

Things haven't changed much since then, she's still all over Mark whenever she sees him, she makes comments like: you sure you're not at least bisexual? or ugh, if I was a guy would you give me a chance?

Jessica's lack of boundaries have caused both OP and Mark to avoid her despite being part of the same club.

Things have recently gotten awkward, because a mutual friend is obsessed with Jessica and thinks OP should give her a chance.

I hate it, he hates it, and we both started avoiding her. A mutual friend, who thinks Jessica is just sooo hilarious and lovely and cute and nice, thinks that we're kind of a*sholes for not hanging out with her. She says we're missing out on so much. And she said she kind of gets it that Jessica is too much for Mark, but that I have no excuse for shunning her and that I'm only being an a*shole.

skahunter831 thinks Jessica is being deeply disrespectful.

NTA at all. Hitting on someone while they're in a relationship, not to mention in front of their SO, is totally unacceptable. It doesn't matter what the sexualities involved are, or whether she is joking or whatever, it's just rude, and not cute or funny at all.

Plus, it kinda seems like she wouldn't do it at all if you were a woman and this was a hetero relationship... somehow the fact that it's same-sex makes her think it's ok? That's extra bullshit. I would tell her that it's wrong and annoying and she needs to stop.

Phatlaces thinks Jessica needs a wake up call.

NTA she’s not respecting both your boundaries. I would be off put also. She probably doesn’t understand how offensive she’s being, someone (not you two) should tell her.

sockmaster420 called it out for what it is: sexual harassment.

If this was a guy doing it to a lesbian girl people would be up in arms. This is sexual harassment, full stop. NTA.

SL0708 thinks OP's mutual friend is being almost as disrespectful as Jessica.

NTA. Just because it's not you being hit on doesn’t mean you have any less of a right to feel uncomfortable too. He has made it obvious he is uncomfortable with the advances and she's the a*shole for continuing despite the fact its unwanted and so is the friend saying you’re in the wrong for shunning her. Someone needs to tell that girl shes actually harassing your boyfriend and the meaning of no.

Hopefully, Jessica gets her due call-out and stops crossing lines, because the way she's treating Mark and OP is not only harassment, it's borderline homophobic.

Man asks if he's wrong for not wanting to hang out with female classmate who hits on his boyfriend.
