Hot or Cold? Red or Green?

[Da In]

So there's this guy that I have never met but think I like. He lives in Utah, I live in Idaho, and one of his good friends is my coworker. One day my coworker sent a picture of me to him because he said that his friend had asked him to point any eligible girls his way. He texted back, 'Not bad!', but didn't really seem interested- he didn't text or press my coworker for details, and I had totally thought the whole situation was over. Randomly, a month later he starts to text me. We texted most days somewhat extensively, although never about anything really deep or personal. He demanded pictures of me on a couple of occasions, and I obliged because it seemed like the non-neurotic thing to do even though I was a little put-off (I don't have Facebook, so there are no albums for him to mull over). Then, four days ago he FaceTimed me without warning and we chatted for about ten minutes. Looking back on it I can see that I wasn't very good at carrying the conversation or being particularly witty or memorable- I was feeling pretty derpy and nervous, to be honest. He signed off by saying that he would talk to me later, and I gave it a day and a half before I texted him a question about something that we had talked about. No reply (which has never happened before). I feel quite disappointed and upset- too much so considering that this whole thing has only been going a couple of weeks. What gives?

I don't think that he's shy, reserved, or intimidated. He's flat-out told me that he thinks I'm pretty and doesn't appear to have a filter- he makes a lot of inappropriate comments even though he barely knows me. I can't imagine that kind of boy would suddenly get cold feet or secretly have poor self-esteem. If he thinks that it wouldn't happen because we're too far apart, why is he only thinking of that now? Was I really *that* boring when we FaceTimed that he now wants nothing to do with me? Was I just something to do over holiday break? I'm 25 and he's 27 and initially one of the things that I really liked about him was that he seemed direct and like he was willing to just go for things instead of play games- surely he's grown out of that sort of thing, right?

Please help! I'm confused and my feelings are hurt. I'd really appreciate any insight y'all can give me...
