Relationship Issues.?

I recently came out of a 1 year relationship, I am 21. She was the first person I can honestly say I have loved. Until now my longest relationship had been 6 months, as whenever I got to the 6 month mark I realised It wasn't going to work with that person and broke up, this time however felt different and I felt really happy even at 6 months, however, 2 days ago, we had a chat and we broke up, there were many reasons for this not that I want to go in to, but we are staying friends, and it wasn't really either of our faults that we broke up, just for various reasons it wasn't going to work, I feel heartbroken and have also realised that it was the perfect relationship for me, we didn't talk everyday as we valued each others independence, we lived about an hour train/car journey away from each other so we would see each other a couple of weekends a month and we were both really happy with this arrangement. The problem I have is as I have never had anyone break up with me before I am really not coping with this well at all, I am going to stay friends with her because I don't want a great year to be wasted, But I don't know how to cope, I just keep remembering all the good times we had and it makes me really upset.

I've also begun to realise that I don't think I can have a short distance relationship as I'd feel trapped and that I have to let that person no everything all the time.

Is there something wrong me? Can anyone help me or offer any advice?
