Someone blocked me on facebook?

ok, so I was talking to this person who lives in a different city than me for about 3 weeks. I really like this person, and they told me they liked me, but I think I may have screwed up and sent too many messages to them. I realize that's a stupid move, and I regret it. But I ended up getting blocked. I also talked to them on skype and youtube. So, my question is, can they get my ip address and find out where I live? and can I get in trouble or anything? Like, do you think I'd get reported?! Has anyone ever done this?!
