I agree with Sluu, it definitely sounds like you guys still have feelings for each other and you need to stop talking to him completely if you want to get over him.. block his number/emails, delete him from Facebook. It's gonna suck and you're going to miss him but you gotta do it. Maybe you *can* be friends down the road but you need space first, I'd give it 6 months at least.

I dated a guy for a while who didn't want a relationship and rejected me, he tried contacting me after a few months and I flipped out- I couldn't deal with it, I was still hurt so he left me alone. I contacted him a couple months ago (about a year after things ended) and we've hung out a couple times, talk here and there.. it's nice to be in contact with him but I'm totally over him now, all the deep feelings I had for him are gone and he's just more of an acquaintance now and I'm totally fine with that.
