<human>: My girlfriend[18F] and I[19M] have been dating for 7 months, we had an amazing summer and everything was great, then we went to colleges, her college was about 45 minutes away so we were limited to seeing each other on the weekends. In the last few weeks of the semester I had noticed she was being a little different towards me, just a little quieter and such, like the flame we had was getting dimmer. We had been fighting this week and last night she told me she wanted a break, that she had been unhappy recently and she felt the need for space and she has trouble creating conversations with me. I said that I feel like it was just the routine of seeing each other on the weekends and such that hurt the most(nothing is worse than planned fun), but she doesn't know if she will be happy again. What can I do?

Can you give me the gist of the text in a nutshell?
<bot>: Girlfriend says she feels different about me, still loves me, but is not as happy. what can I do?
