This guy I Like...

So I like this guy; we've spoken a couple of times now because our families are friends.

Basic background info:

1) he used to fancy my sister (doesn't anymore)

2) he is only 2 yrs older than me

3) my cousin fancies him (she hasn't told me but its as obvious as it gets)

4) I told him I think my cousin likes him

5) I joked around saying I liked him

6) he came up to talk to me when I was alone and we had a great chat

7)he is studying at college 3 hours away

8) I really like him

9) I asked him ( before I realised I liked him) if one of his cousins had a gf (because his cousin and I were practically staring at each other the whole time one night)

10) he answered me (about his cousin) saying that he thinks someone else likes him

I don't know what to do....

I'm genuinely confused and worst is I think I've confused him even more...

Some honest advice would be great!!

I don't want to make a bigger fool out of myself than what I have already....
