How can I tell if a girl is interested in her same sex and if she likes me?

[Serena Elizabeth G]

I'm a girl.
I've never liked another girl before, but I'm very interested in this one girl, and I don't know how to tell if she likes me, how to show that I like her, and whether she's even interested in girls....

If i were you i would try to make a move i mean either she'll like it or not so its a good chance.
