I think that she is sending you all the right signals to make a move. However, the fact that she mentioned her boyfriend can mean two things.
- She likes you and wants to continue this flirtatious relationship, but is communicating to you that she is in a relationship and you should get all ideas about anything romantic out of your mind.
- She is being truthful and is just ready to get out of that relationship if you do all the right things.
You must stick to your original plan and ask her out on a date. You can always start off by saying that you know she has a boyfriend but you are interested in her and would love to date her. I am suggesting this more direct approach so that in case she is totally opposed to the idea of dating you, you won't waste any more time on her (there are lots of wonderful single women out there). On the other hand, if she has doubts about her current relationship, she will appreciate that you are not just a "nice" classmate, but someone who is seriously interested in her.
If she does go out on a date with you, take it slow since she is already in a relationship. Don't rush anything yet, make her feel special, and let her make the decision to dump her boyfriend who doesn't seem to care about her anyway.
