He Just Stopped Talking To Me? (Repost)?

I'm reposting because they had downtime last night so I'm figuring no one saw this. Anyway, I've been talking to this guy I met online for about a month now. He works A LOT so he's super busy but we've been out on a couple of dates, and they both went really well! In the most recent one we went to see a movie and he was holding my hand and laying on me, that kind of thing. Like, his actions say he likes me, but when I'm not with him I don't know what to think! I've been driving myself insane wondering if he is really interested or not, or if he is just really bad at communicating? I asked him a few weeks ago flat out if he was interested, and he said that he is, he's just busy. But now I haven't heard from him in about a week, so I'm thinking is he really busy, not much of a texter, or should I just let it go? I heard guys are not as big on texting as girls are, but wouldn't that vary from person to person? I'm not sure if that's true...:/ And I've initiated contact before, tried to keep it on an equal basis, but I'm worried about coming off desperate or clingy if I say anything at all. I'm trying to think of anything I could've done or said that was wrong, but anything I did/said was playing along with him, so I don't know what the deal is. What do you think is going on and what should I do?? I can live with the fact that he's not interested, I just want to know what happened. I want to ask him if he wants to do something on the Fourth, that I way I'll know for sure, but I came here before I mess up and say something stupid. Please help me. Thank you.
