I need advice about this situation?

I've been dating this guy for a little over 8 months now. At first things seemed to be going great. He was really sweet and caring. He treated me better than any guy ever did. However, within the past couple months, he's been unusually distant, and doesn't seem to be as caring as he was. We don't live together yet-I currently don't have my license (getting it back in May) due to medical issues. So, he drives everywhere. I live in the country, and he lives in a city environment. I have been sacrificing and have been staying at his place whenever he has a couple days off. He won't even consider hanging out in the country because it's "too cold" and "nothing to do." (There are things to do-he would rather watch tv). This past week, I wasn't even home for a couple days-because he didn't want to waste gas driving me back home. I ended up wearing the clothes I had worn the day before the next day. He didn't even offer to at least have me do some laundry at a laundromat and didn't offer me anything to wear. (I'm far from being materialistic-but my sisters boyfriend was accomodating to her when they didn't live together-and I think that he should have at least let me wear cleaner clothes). It seems that he just does things that's convienient for him-and isn't considering what I think. I don't feel as happy as I used to. I know he would be crushed if I were to break up with him. He has even discussed being married to me-but I don't know if I could be with someone who only thought about themselves. Any advice on this?
