Some feelings may be gone for good, or some feelings may just be momentarily forgotten. In a situation like this, she may have her eyes on someone else and that is why she has no feelings anymore. That is just speculation though. You could always try to be a little more romantic, thoughtful, or caring. You could find out if it is something you could fix, but if not, move on. You may be able to be friends, but just as long as you know where she stands. Don't become friends only because you hope she will be with you again one day. If she finds someone else, it will hurt you if that is what you are waiting for. Yes, some couples break up and stay friends, but keep that in mind.
Just be friends with him because if you try to get him to go back out with you then he might not even want to be your friend anymore.
apologize, talk about it, find out her feelings, ask her back out
Take him back
He probably got his feelings back for her
she smiles at her friends behind ur back
Tell her you still have feelings for her, talk to her about the reasons you broke up, and how you can prevent it happening. don't give up easily. good luck !!
* You should communicate with him right away. If you broke up in a bad way then you should explain yourself and apologize to him, but, if it's over then tell him. Be kind when you express your feelings and why you broke up with him and tell him you do not want him to bother you any longer. Don't let him talk you into coming back into your life.
dump the new one
You cannot do much about that. It is their decision and you can't hinder in their feelings.
If they are being physical then hurt them back. But running away is best.
get over him unless he breaks up with her.
Because you probally still have feelings for that person. Ask them back out if their not in another relationship or if you guys broke up for something really bad.
