How do I get him back if he has a new girlfriend?

I broke up with my boyfriend about 6 months ago because I needed some space at the time. I've started liking him a lot again and I want to get back together with him. There's one problem- he has a new girlfriend. I know he likes her but I have a gut feeling that he likes me too and he also flirts with me a lot and I sometimes catch him staring at me at school. I want to tell him how I feel but every time I'm ready to I chicken out cause I'm so nervous about what might happen between me and him and me and his girlfriend. (btw- his girlfriend spreads rumors and gossip and she is also a major drama queen) How do I tell him without getting hurt? And if he doesn't feel the same way how can I make him like me more than his current girlfriend? What are some scenarios that could happen if I tell him how I feel?

ummm you cant make him like you again if he has a new girlfriend... thats just not possible for the time being. because he's in luv with someone else, not u.

You just have to wait until he's single again... it'll happen...

Its been 6 mos. You cant expect someone to wait around for you, then expect them to come back when you want them back. He has moved on, and you should too. Respect him, and his girlfriend, and just keep your feelings to yourself. Just think if you had a boyfriend, and some girl poured her heart out to him...how would you feel? You let him go, and now hes with someone else. If/when he becomes single again, and you still have feelings for him, then you can let him know, but for now, keep your feelings inside.

I have this guy just like this I broke up with him he is going out with my best friend and I told him I like him and he said hed break up with her for me but I dont want to hurt my friend adn my friend knows I like him.
