<human>: Can you succinctly summarize the text in 1-3 sentences?

Around 4 years ago I found this amazing girl and we dated our whole first year of high school. We fell in love, but never had any sort of sex... not even sure if we made out ever. I had to go to a boarding school so we broke up at the end of first year because we couldn't handle it as we weren't mature enough at all.

A little more than a year ago we got back together (long distance about 200 miles) and had our problems, but everything was great for the most part. We had clearly matured, we still loved each other, and it was like a fairy tale how we could get back together and still love each other so much, the difference this time is we had sex. 

Our dates (once every two weeks) would consist of going out to eat, doing something fun, then we would find some time for oral or whatever presented itself. About 2 months ago I moved back near her and we go out on dates more often, maybe 2/3 times a week. We fight a little more but only because we are around each other more. Our dates stayed mostly the same, until recently after she was finished in bed it was 'my turn', but instead she simply put her clothes on and just said "I don't want to". Now since I didn't want to sound like a complete douche I accepted that for what it was. But then, on the next date she tells me she thinks it would be better if we not have sex anymore, saying we rely to heavily on it. 

I don't really know how to approach the subject without sounding like I only want her for sex, I feel like I'm in am unfair position. Obviously as an 18/m my hormones are crazy and I'm just ... used to it. I love our sex, I don't/didn't think anything was wrong with it and it made us both happy. Help me help us please.
<bot>: Me and my girlfriend had/have a good sex life and she thinks we rely on it too much, so she does away with it completely.
