Pay attention to who he gets more enthusiastic about. You, or your freind. He may not even be flirting with her, mabye you still have a chance. Or, mabye he doesn't like you anymore and you should look for another boyfriend.
Ask yourself this. IF he is your exb, do you still like him. If you see him flirting w/ another girl, talk to him and tell him that you still have feeling and are willing to try again.
You can tell your friend that you have some feelings and not to be all kissing in front of you or I like you more things.
she wants you to still be in love with her, even if she has a boyfriend.
Talk to her.. If she's your friend, she shouldn't be flirting with your boyfriend. Or, if she's just some random chick you don't know, she still shouldn't be flirting with him. If she is. If she talks about him all the time, somethings up. Talk to your bf and see what he has to say about it.
There's a possible chance it could mean that but it doesn't always mean that. Ask her if she likes him.
forget about him
If you are in middle school and a boy flirts with you, but has a girlfriend, you should ignore his flirting. Even if he likes you, he still has a girlfriend. You should respect his relationship with the other girl since you would not want him to flirt with another girl if he was your boyfriend.
He's just horny :P lol
maybe she likes you or maybe she's not use to seeing you with other grls yet. cuz it's kinda weird when you get out of a relationship and you see ur ex flirting, well i think it is.
well he obivosly still cares for you cause he lost something he cared about dearly and trying to move on by dating another girl but can't recover by seeing you hanging out with guys or flirting.
Well,the best way to tell is that he'll give you that "look" and he might start flirting.
You might have made him nervous and he got scared but he still likes you but doesn't know how to get over his nervousness.
