You're the only one who can decide whether to act on it or not. That being said, you also have to consider whether or not the feeling is mutual on her part.
If ur ex is BFF with ur crush try and make ur ex like u. Try to be Friendly and generous. The way to tell ur ex and u are friends u will no longer call him "my ex" if that makes sense. Then haNg around with your "friend" and get to know ur crush more. Become close friends with ur crush then flirt. Either u or he will soon make the first move. Magic.
Two things: 1) Your ex would like to start a relationship with your crush, this is what happens in most cases or it could be theory 2. 2) The Ex would like to make friends with the person you have a crush on, the problem with this is the Ex could tell some lies that may push the "crush" away from you and closer to the Ex..
"Ask him out when your best friend dumps him." ^thats the last thing you should do! if your a friend, you don't grasscut your friend! never date your friends crush or ex!
friends
OK, this is hard to tell you but you may remind him of his crush or of his ex-girlfriend. From: C.A. Cupid
Ex: I have a crush on that new boy in school. Ex: I want to crush the kid next door for making me angry. Ex: Hey Elizabeth, did you crush the peanuts?
If he is not keeping in contact with his ex crush then you are simply borrowing trouble by worrying about. If he is in contact with his ex crush then you should make it plain to him it's either you or her. He has no reason to keep in contact with her and if he refuses then move on with your own life.
think about your ex-crush in the nude, if that does do anything for you, the crush is dead.
wow, didn't know they all liked the same person, but the answer would be no, my crush is not over their ex.
Why don't you just talk to him yourself, instead of getting your friends to talk to him. That is the only way you will ever really know if he likes you or not.
It means your friends have noticed your crush is always staring at you.
If you keep having dreams about your ex or your ex crush then it means that you still have feeling for him and you don't know it or don't want to admit it to yourself or it could mean that you are still in love with your crush even though it was in the past.
