The fact that you were in love with him, but he didn't care at all tells you everything you need to know - he doesn't deserve you. Move on and find someone who does!
Forget him. He is not worth your time or your effort. If he really likes you he will do everything he can to get back into your life and then you decide from there if you want him or not. Trust in the saying, "everything happens for a reason"
I don't know how old you are, but how about both? Forget him, then try again! It took me a long time to find the person I belong with, lots of bumps in the road, but very well worth it when you find him! Good luck!
He is gay but looks so straight
