Sorry but as a bi woman they have a point. The “I hate my boyfriend” jokes are a little 😬. Though I think the OPs should have some sympathy for the fact that a lot of that comes from internalized biphobia and a desire to fit into the queer community, not bc they are trying to “virtue signal”
Ppl shouldn’t be making jokes to make you feel bad for who your with and also its weird to constantly make jokes about hating who youre with, how would you feel if your partner kept making jokes about not wanting to be in a relationship with you to his friends? In front of you or not I don’t see that as acceptable
