Stay out of it! You had your chance with her and it didn't work, so as long as her boyfriend is still around it's best to move on. If you find you still love her in a few months then the only time you should feel free to try and win her back is when and if she break-ups with her boyfriend. Yes if you have feelings for her you need to at least try to get her back.
He is a very unsure person. And you should be careful, as he can easily go back to the old girl for good.
There is nothing you can say that will guarantee your ex girlfriend will take you back. She has a new boyfriend and may be totally over you.
she still flirts with because she is probably trying to make her boyfriend jealous... or get him back for something he did.
If he is already your boyfriend chances are he like you. But if want to see if he really cares about you ask if he would still care about you if you moved or something like that
Protect your self dont wanna get pregant as his ex girlfriend do you?
maybe its because they still have feeling for there exgirlfriend and the girl may not love them back. some boys do get upset about that!! Or they just dont like the fact she has found someone better than him. maybe not they may not like the fact that shes moved on and he just cant
You can talk to him about him liking his ex. It might be the case that he is missing her. If she does not come back you can give all your love to him.
i still like you and i want to make you happy just like you do to me everyday hope it works and please recommend me!
Patience. You shouldn't expect her to like you as a boyfriend if she already has one but you can still be a non boyfriend.
tell him that you are already taken and in-touch with your boyfriend (if you are in touch) then he will understand he is too late and will either wait or move on. or if he is mean he will sabotage or something
then she should leave her boyfriend and do something about the love she has for her best friend..
because he might still have feeling for you or he might have something to say to you.
