shes hideing something, you said her reason was that the two of you cant be together anymore.

Did you ask why that is?

From past experience I can see this being a pre-imtive strike on her part.

Thats saying she is trying to save herself pain down the line from the likelyhood you will hook up with another at college.

It's also not uncommon for couples to go thru a stage like this when a seperation is forthcomeing, I was in the Navy and I went to a couples siminar on seperation cycles because I was being deployed on the ship for 6 months.

In the cycle its not irregular for there to be this sense of anxiety based on things that may or may not happen. Useing a metaphore, its like building a wall between the two of you in order to not feel so much pain when the time comes for you to leave her behind. This explains the down hill rolling effect of the relationship.

You seem to be pretty aware of your emotions tho which is excellent, take this opritunity to grow from the experience.

If you make a move like the ones you see in the movies, you just may be setting yourself up to be locked into something simply because you dont want to deal with the pain of the loss.

OK, my Dr. Phil moment is over, good luck man, I hope what ive said can help you. I'm sure there are books you can get to better help explain the phycological cycles im talking about.

Peace.
