Most Helpful Girl
I'm a pretty blunt person, so I tend to be honest regardless.
I've told guys I liked them before - most said they weren't interested, one way or another. One even said no because he doesn't like girls that make the first move.
There's really only one person in my life that I really liked but never told, and I never told because he had (still has) a girlfriend (they've been together for 5-6 years now). I don't go after taken men, so I felt telling him would be crossing a line.
I think it should be a fair game. If I like a guy and he hasn't made his move yet, I'll make mine.
