They keep looking back at you. They constantly call you, talk to you, etc. They seem nervous around you. Blush, talks about you constantly with their friends.
you know that your over him/her if you realy dont think about them a lot.
you know there over you if they flirt or date other guys
wow, didn't know they all liked the same person, but the answer would be no, my crush is not over their ex.
amount of time you think of him/her
If he has nothing to do with her and you have the trust in him when he says that he is.
you dont
When your ex doesn't ever talk to you. sometimes your ex might just want to be your friend though
When he goes out with somebody else and he says that it is over between you and him or you and her.
tell shim to leave isnt that obveous
amount of time spent thinking about him/her
Usually when they become your ex that would be a good indication but in addition that there is just nothing more to say.
'Ex' means the relationship is over and you have answered your own question 'you're over your ex' so stand on your own two feet and nicely, but bluntly let him know you are not interested in getting back with him.
