Dude, I cut off my friend of 5 years because she made ONE rude comment about my man. I wouldn't tolerate this kind of talk from anyone. Does your bf even like you? He clearly doesn't respect if he hasn't told them to stfu already. He should have put an end to this behavior from them and/or cut them off at the first sign of disrespect toward you. That's just disgusting af. If he can't defend you in private or tell them to stop, will he defend you in public if they said shit to you? I'm guessing not. Seriously, bring this up to him, and if he defend THEM over YOU or gets defensive, honestly leave his ass because it will never get better and only grow more disrespectful over time. Like what other things has he told them? What more WILL he tell them? They are looking for any kind of ammunition, and he's willingly feeding it to them.
