I'm really mad at someone, how do I let that go?

I'm mad at someone who dissed me. I realize I am a better person than he is. Both in physical beauty and personality wise. He has a real shortcoming if you know what I mean. I was overlooking all of these things because of his sweet talk. I thought I should look beyond the physical and focus on inner beauty, apparently that is just as bad as the outward appearance. It's just I am so irritated that someone would tell me all kinds of sweet talk and then treat me that way. How can I just let it go? For most people, this wouldn't be that difficult. But, I'm all alone with no friends near me and I'm not working so all I have to do is sit around and think of this...and do my stupid job search all day long. I'm just angry that someone would lead me on and disappear. Especially someone who I was liking for his personality and forgiving some major flaws like: obesity, poor performance in the bedroom, less than average toolbox size, and mountains of extra body hair that only a weed wacker could tame. His back was hairier than his chest. The thing is, I had unprotected with him because I thought he was an honest guy. Now I know otherwise. Please tell me how to get over my anger and relax over this whole thing.
