You can't. Since he is your "ex", you and he broke off all relationships apparently, and he has decided to move on ... so should you ... Next!!
Go with them and make him a friend.
It means the ex boyfriend still likes the ex girlfriend.
if you did it isn't a good idea
You go up to your boyfriend and tell him to choose, but if he can't then break up with him. Why go out with a guy who goes back out with his ex if he has another boyfriend.
be yourself
She probably did it to make the ex- boyfriend jealous.
He had a girlfriend. Her name was Kasey. They are not boyfriend and girlfriend anymore.
she flitrts with you while they go out
im sorry to say but get over hes gone
No, you should not email your ex girlfriend to try and get her back because she has another boyfriend. You had your chance to make the relationship work out with her and since you didn't then it time for both of you to go your separate ways.
Nothing. He has a girlfriend. He did not say he wanted to go out with you, he said he likes you. You can like someone without wanting to go with them.
If it is an ex-boyfriend, then it shouldn't matter...right?
