<human>: Background about us : I've known her almost my whole life, our families get along really well, we both know each other's families well also. 

We've been dating since the end of December 2014 and I recently brought up concerns about her leaving for college at the end of summer. She is moving 6 hours away to the eastern side of the state, and I'm worried that things won't work out well.

I'm a very physical person. I like to hold her, touch, kiss, go on dates, things like that. She says that she can have people stay for up to three days in her dorm. That's great and all, but I'm still worried.

What about all of the guys? I know she's loyal, but not seeing me in who knows how long, and having all these college guys around? 

I'm not saying I wouldn't be tempted to either. I also go to college, there's also a lot of girls here. I would be missing her even more with that.

After voicing my concerns to her recently, she's become very distant. We used to have a very active sex life, always doing things almost daily. Now we haven't done anything more than a kiss. And those kisses feel distant and cold.

I talked to her tonight about it, and she says that now she doesn't want to do anything sexual. She used to always talk about all these crazy things we'd do in the summer, and now she says she doesn't want to do anything.

I don't know how to react. I respect her of course. I recognize that it's her body and that I'm not entitled to any form of sex at all. I understand that. But after doing so much and her talking so much about summer, and then I randomly voice my concerns, she doesn't want to do anything more than kiss me, I feel almost betrayed.

What should I do?

Give me the gist of the text in a nutshell
<bot>: She's leaving for college soon, I say I don't think things will work after that, she says no to anymore sexual activities.
