My best guy friend...?

Okay, so... I have this really good guy friend, his name is Eddy.

The other night, like, last Tuesday, he sent me this text saying that we needed to talk. I was out of bar-range so I emailed him back saying that I couldn't talk because I had no service. He then emailed back asking if I could see us together next year (as in December 2010, not January) and I said sure, but asked why. He said that he had been thinking about me a lot because he missed me and he could see us together. I then talked to him Wednesday and he had gotten back together with his ex. I don't know how to react to this. I'm kind of pissed, but at the same time, if his ex is what's good for him I want him to be with her. He wants to see me this week. I don't know what to do. Please help me and give me your views on my situation and of Eddy.
