How do I know if she likes me?

Re: How do I know if she likes me?

All of these girls are very attractive, it’s just that I don’t like to talk much so I don’t understand women and I only want to pursue a girl if I’m 100% sure she likes me cause I don’t deal well with rejection. As for race or religion, all of these girls are from different backgrounds and to me it doesn’t matter much.

My question is for the ladies, what does it mean when you do any of the stuff I mentioned? Does it mean nothing?
