Extremely confused...any help would be most appreciated (girls preferrably)?

I'm a guy but I know what I'm talking about... First off, she's still interested and you know that. If you can't see through all the signals, than you're blind- no offense. The eye contact, the emails, etc. It is all to get your attention. Especially the fact that she told you about the other guy hitting on her, it was all meant to make you jealous. Jealous so that you could want her even more. She wasn't trying to hurt your feelings, simply just to get your attention and to see how you'd react. If you truly have feelings for her, go for it and if she truly has feelings for you, than she'll come around. Don't be too available and back off a little on pouring out all of your feelings. You need to begin making her want you.
