Why is he like this?

I was dating a guy for nearly two months, after I had to move from my apartment I needed a place to crash for a bit because I had nowhere else to go. He was kind enough to allow me into his apartment while he was away on vacation for the holidays. I was here for about a week alone until he came back on NYD. When he got home that day he was the usual, a little sad he had to come home from vacation but we had pizza and beer and things seemed normal. After a few beers he tried to have sex with me and I said no because I’m having a hard time and I’ve learned having sex with people you don’t know well isn’t a good idea. The next day his personality did a complete 180. He hasn’t spoken to me, he doesn’t look at me and completely ignores my existence. I’m leaving Tuesday but, it’s strange and I can’t say it doesn’t hurt to be treated with such contempt.
