What signs do girls give if they like you?

[mobile]

Right well there's a girl I still really like even though we broke up about 2 months ago, I dont know if she still likes me or not.

I was thinking of talking to her about it, but I am too afraid of rejection.
Are there any particular signs girls give off when they like you?

thanks

Um, usually paying quite a bit of attention to you, esp. when you are in a group of people, smiling and giggling etc. ... yeah, not too sure there sorry. XD Will post more again later if I think of something.
