What matters is; does he like you back? If not, it is over. If he does, then what is he doing crushing on another girl? Either way, you lose. Get over him and move on. If you like him/her enough than u cld wait for him and tell him you still have feelings for him/her. If the relationship has ended and one of you has moved on then it wasn't meant to be and you should attempt to move on as well and find someone who truly cares about you, even though it may be extremely difficult.
why, he is your ex right
forget him and find someone else
It depends on whether or not he's with someone else. If you're a guy trying to get an ex back look up 'How to get a girl to like you?' and if you're a girl trying to get an ex back look up 'How to get a guy to like you?' Very accurate answers!
get over it already
It means that he likes you. If he was not kissing you back, then that would be obvious that he probably likes someone else or he doesn't like you in that way.
if she/he is hot then yes.....unless your going out with someone else.
What will you do with your ex. He will never be the same with you. You should better see someone else .
Nothing. They are your ex for a reason let alone they are with someone else. Keep going and don't look back. Think of all the future opportunities.
sounds like someone is a gold digger
You go rape her, and fist her.
She probably wants you back.
kill his or her boyfriend,"simple"
