What should I do to deal with this?

I had hooked up with a coworker since I did feel a little attracted to him. We never actually had sex but we touched, caressed, and we would have dry sex. You know he would rub his private against mine. The thing is I've never been sexual with or even kissed a guy. So maybe there is something wrong with me. Anyway back in November, I emailed him telling him that this FWB is over and that I would tell HR on him if he ever suggested hooking up. Since November, I've been ignoring him completely no hello nada. Since I was so mad and hurt. Last month he went out of the country, I was actually relieved that he was gone, but then he came back last week and I kept ignoring him until yesterday. Yesterday, I saw him in the kitchen and he said hello, you know like a mechanical/ break the ice hello and I smiled and said hello and that was it. I felt completely at ease. This morning, I ran into him and said hello and he didn't say anything. I emailed him saying that I was hoping we could be on speaking terms since yesterday I felt at ease with speaking to him. He ignored my email. He actually didn't bother to open it and looked at me like a freak. I personally confronted him and he was like fine. As the afternoon progressed, I did a lot of walking by passing his desk, but I didn't bother to talk to him since I was working. As I was walking back and he was leaving he gave me a somewhat dirty rude look. I personally thought that was rude and I sent him an email stating that I thought him looking at me funny was rude and that I was hurting these past few months and that I was hoping we could get along as coworkers. Then I sent him another email that it was best that we didn't talk and that he should leave me alone and let me do my job. How can I move past this and get out and get some friends and a boyfriend? All I do is work and go to school, but I feel if I were getting out with people. This would be easier to deal with.What should I do to deal with this?
He is wayyyyyy ahead of you. Stop communicating with the guy. Obviously he doesn't want to have anything to do with you if he wont speak to/return your emails. He's doing you a favor, just STOP trying to communicate with him. You probably upset him by making the threat of ratting him out to HR and that is why he will not speak with you. I am not saying that that was a bad thing to do. However, you could have handled the situation in a more professional way. Act indifferent towards him, ignore him, and LET IT GO! you'll get over it in no time.What should I do to deal with this?
i would give you funny looks too.

tell me to leave you alone, tell me you want to be friends.

just leave him alone.
I think you're a little trigger happy with your texting. By the sounds of things your feelings were mutual at the beginning, I'm not sure your motivation for threatening him with HR like he's sexually harassing you -- I wouldn't be too happy about that. So you like him, you don't, you're ignoring him, you're not, and then you want to ignore him again....What is the guy supposed to feel other than confused and annoyed? Walk away from this mess and start fresh with someone else and play it straight this time.
