Hi, recently unexpectedly know a girl through a friend and kind of like her a little. Through a little contact and luck managed to get her no. and msn. Well, it seem so far very bad, me isn't myself, got a gut feeling that she do not like me and instead it seem she is interested with my friend instead who is currently in love. Well, kind of complicated. I have no idea what to do and always wanted to give up but I just can't forget about her. Advise.

Sounds like you made an effort to let her know your interest and it is her turn to let you know if she has any interest.
Let it go until she replies cause if you keep after her she will consider you a nuisance.
