What's the rush?
You're at college, go with the flow and see how things go
Talk to people, get to know people
Opposite sex will be doing the same
Have some fun and don't worry about each person you cross eyes with
If you don't like the way he treats you or his lack of response
Find someone else to fit your sexual needs and companionship
Sounds like you have a lot of good things going on and it wouldn't be that hard to do
Maybe she is tired of telling the story over and over.
Find some new things to talk about
Find ways to brighten her day and get her back to being happy
Or she's not over this other guy yet and doesn't know what she wants
