Most Helpful Guy
She wants it, she wouldn't even come to your room, spend time with you or even talk to you if she wasn't.
You need to introduce physical touch slowly (but asap), like sit next to her, touch her arm , leg, anything. Playing with her hair and fixing her clothes, giving you direct eye contact, all direct body language signs she is there for something more to happen. You are one lucky guy so don't wait to long and waste this chance if you want something to happen as well.

In my experience, one friend always likes the other friend more than just as friends. When she makes those eyes at you, ask her if she is flirting with you, cuz it looks like she wants you to kiss her. See what she says to that. Unless you want nothing to happen. If that is the case, ignore it.
