Ignore him, sounds like he's just trying to rattle your cage. If your girlfriend cares for you that's all that matters. If you have a good looking girl, there will always be some AH trying to get in your way.
Cut them off
you should apoligize t your friend and his girlfriend
If you two are genuine friends & nothing more, yes. There should not be an issue. Just remember to be respectful of his relationship & his girlfriend.
get to know them better
if there your real friends then they would be supportive of your relationship, and you shouldn't let your friends make fun of you girlfriend. remind them who has the girlfriend around here, And maybe they should get a girlfriend. But if you tell them to stop and they won't then forget them.
no not at all
if all your friends shout " do it do it do it" over and over again
Do you trust her? Sounds like you don't... And you should be proud that she's your girlfriend. She's obviously a catch if guys are constantly talking to her...
I think you should talk to your boyfriend and tell him to have a little chat with his ex.
when the ex girlfriend is dating your brother or friends. that pissis me off it happened to me thats when all of my friends stop being friends with the ex and my ex bestie.
Don't avoid the problem ask him straight out what he wants. Tell him how you feel and go from there. He might only be sending you mixed signals because he doesn't know if you like him back
of course you should its a great opportunity to make friends
