What do i do?

I met a guy last night. An aquaintence of a friend of mine. He seems really nice. I ended up giving him my number. It was unusual for me. I actually made a move on him... and tonight im second guessing myself. Im usually more careful...i dont know what possesed me. Other then i got caught up in the moment, because he seems really nice and i would really like to get to know him...its not because of him, but because of me. Im such a mess, my life is a mess. How do i willingly bring someone into that. (granted, that is assuming he calls me, if not, im worrying about nothing) But if he does how do i go about this? I just dont know. I think it would be very selfish of me to bring him into this, this, for lack of any better wording...mess. Theres just so many problems im fighting...how can i expect someone to deal with them too? I guess ill just have to see if he calls first... then ill worry about the rest later.
