Most Helpful Guy
Is there any specific reason as to why he stopped talking to you. If you have feelings it could easily ruin the relationship again if he doesn't feel the same. I'm currently stuck in the aftermath of it. If you really want to keep him as a friend, move on from the feelings you have. Don't end up in the situation I'm in.

These kinds of things can be complicated, but it's better to protect yourself. If you want a long answer, think about how to answer these questions
How does his treatment of you make you feel?
What does he add to your life?
What does he take away?
What other things could be happening in his life right now that would cause him to seek you out?
Does he want to be friends again or does he want anything physical?
He broke your trust by leaving the friendship, and he obviously has a reason why he stopped talking to you. I don't have a good feeling about this and I would proceed with extreme caution. Protect yourself, and stay in the present. Don't worry about how he treated you then- think about how he's treating you right now, and decide if you want that kind of thing to continue.
