Guys, I know that being the way I am doesn't make things easier if a guy likes me and wants something with me.

But this is also a way of finding out if the guy really is interested on not - I guess I don't open myself very much because if I give too much away, it might ruin things, mainly if:

1- He's not interested at all
2- He isn't looking for a serious relationship

If this guy I really liked was into me, he should've showed it - but he didn't - well, neither did I, but generally, and, at least, on my point of view, boys should be the ones approaching us first, although to you this may sound a bit old-fashioned, but thats how I work.
I mean, he didn't give any specific or obvious hint that he liked me more than just a friend, you know? How could I dare to show affection to him then?
I know - it's a risk that's worth taking...but I don't seriously like the idea of giving my self away to a guy that I don't know if he likes me or not.
