I'm having dreams of him A LOT.?

I wouldn't force anything. Go with him if you want to, but make sure he isn't just using you. I would encourage you to confront him (gently) about why he deleted you from facebook. If he can't give you a good reason, I wouldn't kiss him or anything. Just get to know him again. First boyfriends are tricky to get completely out of our heads. Good luck!
