Relationships

I asked him for space, I miss him. Need some advice.

so basically we started off as friends and we finally had sex after 3 years of friendship. to him he said it was just ex and he walked off saying my feelings were fake. and I wasn't faking when I said I really care for him. he said he'd always care for me but he doesn't see me in that way. I really feel sad and frustrated. he later texted me to ask how I was and I wouldn't respond. I think he's hoping it out that I would just remain friends with him but basically I don't think we can be friends since I feel awkward around him now. it wasn't suppose to happen like that. I would have preferred it if he was dating me and he wanted me to be his girlfriend. he moved away for schooling and basically said to give him a year to figure it out because moving is expensive and if he doesn't like it where it is, he may move back. I feel part of the reason why he refused to continue a relationship is because it would be long distance and maybe there's something I can work on so that he'd feel the same way. he said I'm beautiful /hot and sexy and I feel happy with him but I did cry the next day because I knew we'd be long distance. he might have been confused by that. it's been a few weeks after I asked for space and he respected it, but I feel like we're no longer friends. should I date other guys or wait for a year?

and I guess this is also a small question, but I feel like I'm a fool for falling for my best friend like this. If he cared about me, why would he make me feel this way? if he didn't have feelings 'like that' in the first place, why do I feel like he took advantage of me liking him? I wish there was an easy answer or solution to make myself feel better. thanks for mature answers.
