Dravaza. please. I don't know who you are, but that was bloody unacceptable.
Hmm....
I think you should be friends with them first, see where it goes, then maybe after a month or so, or two. to be safe. see if there is still is something there, if not, then don't ask, and continue being friends. However, if there is something, and you two both feel it, then start seeing where it leads. take it slowly. that's a good idea. Don't have sex right away. that's the best advice.
