Most Helpful Guy
It's normal to feel that way, you want him bad cause you can't have him, it's called obsession, don't do that to yourself, your better than that !!! His loss, let him go. Soon you'll find a better guy who loves you for real... You won't even remember his name.
So the answer is no, all that can happen now is he will use you again and go back to another girl. So don't go after him...

If he texts you, tell him you don't feel right communicating with him when he has a girlfriend. Tell him you aren't sure why he just cut it off with no explanation and that you don't need that in your life, you would rather do you and eventually find a real man. Then do your thing girl. That should open his eyes and if he wants you give it a month then try to work it out again. But boys don't change.
