Don't try to keep a hold of him. Give him a little room and don't try to put your self out just to get his attention again. Yes things may feel all jumbled up inside you and your hurting but if he really actually likes her instead of you then he would usually leave you. But if you give him a little space and show him you still care for him (but not in an obsessive way) and he still feels something for you, then he'll stay with you.
If you're close enough with him to talk to him about it then do so but if he doesn't feel comfortable talking about it be sure to not push him and then end up loosing him whether he actually likes this girl or not.
no affense but what you have to do is suck it up and find another girl you like.well you know what they say if you love something set it free and theres another saying.....there are many fish in the sea
you flirt with him and talk cute
give up
Wait and see what happens.
Forget about her till she is alone again
not technically, if he is really interested in you and you bring your relationship further it mite turn into love. if he likes another girl.......well i would move on
Same as he likes a boy. They blush and they care.
Dump him.
He likes the girl he kisses unless it was an he didn't mean to kiss that girl. or he likes the girl he kisses and lies and says he like someone else
try act cool to the guy !
may be the girl ignoring the boy who likes her
she is simply a lesbian.(wants a girl/woman likes a girl/woman she is a lesbian)(wants a guy/boy likes a guy/boy then he is a gay)
If the girl likes the boy looking at her, then she likes it. If the girl does not like the boy looking at her, then she does not like it. It depends on her feeling towards the boy looking at her.
I think that the best thing to do is to tell him. Sure, he doesn't like you, but he deserves to know how you feel
