BEST ANSWER GUARANTEED: I can't do this whole relationship thing...any advice?

I can't for the life of me tell when someone likes me. I'm attractive, I know I am and I am widely regarded as attractive. But I just can't tell when someone is into me, I'm always a mile off. I am a huge flirt but then if I suspect someone is interested I back off. I freak out, become unsure of what I'm doing. What also annoys me is I can get guys no problem if i "switch it on", but I have pretty much given that up because I don't like being phoney. I have an awesome personality and I'm loved by my friends and I pride myself on being who I am, so I want guys to like me for being that person. I often wonder if it works against me though. I've got a sense of wit like the mom from the gilmore girls! It's rare for girls though, I've been told many times. I don't know if guys like it or if it makes them feel like I'm not feminine. Even though I am very feminine. Ugh i'm frustrated. Help!
