Read your own question very carefully. Are you suggesting that your ex is somehow in charge of what you do? What you do has to be related to the fact that he says he likes you again? What do you want? As the saying goes, he is not the only fish in the sea. Now, I'm not saying that you need to drop him, because who am I to control your behavior? The point is that you need to get a grip with this, and decide who is calling YOUR shots?
He Likes You
nothinh
Nothing. He has a girlfriend. He did not say he wanted to go out with you, he said he likes you. You can like someone without wanting to go with them.
Flirt with him, show him that your still interested and want to be together again.
not worry about it. its ur ex
just tell your new boyfriend that you still have feelings for your ex and tell your ex that you have a new boyfriend if they really care about you they will understand
* * *
ask him
It means the ex boyfriend still likes the ex girlfriend.
Treat her better then her boyfriend did and she will see you are a better person
She already said she likes you.
He probably doesn't
