When you stop thinking about him/her!!!!!!!
EDIT: You don't necessarily have to stop thinking about them to be over them.
You will know when your over them, you will stop hurting, you will be able to move on and be with someone else without comparing the two, you will be able to forgive them and talk to them without any resentment.
you dont
he cant really like you if he is your ex he will be trying to get back with you then
if you know that then why dont you get someone else that really likes you that would never cheat on you
Ask him.
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
If you really like the guy go out with him.You and your ex are over...
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
Getting over an ex takes time. But you really should already know by how you feel about the person. I think that to really be over an ex then all feelings of that person shouldn't exist anymore. For example if you were hurt by this person and you still feel anger towards them or even hate then you really still do care about the person and are not over them. Or Did you hurt the person and maybe you still feel guilty or bad about it then again you really arn't over them. To truly be over an ex is to be able to think about them and really not have much feelings towards them. So sit back and just think about your ex. Ask yourself how you would feel if they got married? If they moved far away? If you would never see them again? If you have strong feelings towards any of these questions then you really arn't over them completely.Also sometimes if you feel you don't know. Try dating some new people. If you start having strong feelings towards someone new then perhaps the feelings for your ex are drifting away. Good luck hope I helped :)Moving on.when you look at him one day, and he grosses you out, and you wonder what in the heck you ever seen in him to begin with! Booh-kitty says.......When you find yourself not thinking about them or wondering if your over them anymore, then you're over them for good!
Talk to him. That is really all that you can do.
You won't care if they're dating someone else. You don't feel anything when they flirt with other girls/guys.
