First off, let me explain my story a bit...There's this guy that I know on another online forum who I've been friends with for quite some time now (though our friendship is pretty much just online). Back in May, I met him in real life for the first time. When we met, we ended up hooking up, though we couldn't actually have sex because he forgot condoms. Shortly after that, I noticed that he seemed more distant in his communication, and he finally told me that he couldn't do a long distance relationship with me, which I understood. (Though I had never mentioned anything about a relationship. I just asked him what our meeting meant.)
Well, after that, his communication with me went back to a bit more normal. Eventually, it started to move back to more flirtatious stuff, and he brought up how we never got to go all the way the last time we met. He hinted towards coming to see me again so we could, and I went along with it because I do still want him. Even if it can't be a relationship, I want to see him just this once. This went on for quite awhile but he could never seem to tell me when it could actually happen. I pointed this out to him and said it almost seemed like he was just joking, which led him to send me a picture of himself which suggested otherwise.
Well, after he sent me the picture, I asked him when I'd be able to see him in person. That was the most direct I had been with asking him when we could meet. He still hasn't given me any kind of answer and I asked him over 2 weeks ago. We've talked a bit since then, though not much.
Now here's the important part...
The last time I talked to him was past Thursday. We had a very short conversation through text in the afternoon. In the evening I sent him a text asking again when I'd be able to see him and since then...absolutely nothing. No texts, no private messages through the other forum, no conversations on the forum, nothing. I know he's been on his computer because I have him as a friend on Steam and have seen him playing games there. I've sent a couple messages through Steam just trying to initiate conversation but again, no response. Saturday was my birthday and he said nothing then, even though I reminded him through text. I have no idea if there's a problem with his phone or something but either way this total lack of contact with him is really upsetting me

I'm worried that I freaked him out by asking when I'd be able to see him and now he's trying to avoid me or something. The fact that he's been like this in the past adds to my worry. He's
never totally ignored me like this before but I still have to wonder.
How can I get him to say something to me? I've already sent several texts and don't know if I want to send more. I don't know what to do.
