Break up after 2 years

LegacyUser

I've posted here in the past about my relationship issues, but am in need of a bit of help once more.

To set the context, I've been going out with a girl for just over 2 years now, and was seeing her maybe 6 months or so before hand. I'm just turned 21 and she's 4 years older than me. We worked together for most of that time, I was in college working there part time and she was full time, this is where we first met. She had been in two relationships previous, and this was my first.

It started with just kissing on work nights out, and progressed to a closer relationship. It wasn't without it's fights and lows which I'm sure is normal, and the good times were really great, but it's gotten to the point where I'm not enjoying any of it any more, I no longer feel the feelings I felt at the beginning and find myself never in the mood for sex or even cuddles anymore. To make matters worse, she doesn't get along with any of my friends, she never did, no matter how hard I tried to help them get along, and she gets very jealous when any of my old female friends talk to me or post on my facebook page etc. We see each other between 3 and 5 days a week, and days we don't she calls me for at least an hour. All through the day she texts me. I have never been a big texter or even talker on the phone, and don't enjoy this at all.

About a year ago I tried to tell her I no longer loved her and that we should break up, and was subsequently bullied into taking a week long break and giving it another shot. She responded quite agressively to the situation, slagging me, and ringing/texting me constantly after I had left. It was made harder by the fact we were still working together and had to see each other the next morning. I agreed to the break. She still rang me every night of this 'break' to talk, and we got back together. I hate to say it, but looking back I just grinned and beared it for the past year as I was in my final year of college and had exams to worry about, I know this has just made things harder for both of us.

Cue last night when I called to her house to tell her, she was very upset, we both were, but she took it a lot better than last time, there was lots of crying and a a lot of silence, I was with her for nearly 3 hours and when I left I got no calls or texts. I woke up to one she had sent during the night telling me we have something special, and that I can't just throw it away like this. I have been trying to tell her that I will inevitable feel like this again 6 or 12 months down the line and it will be even harder then, but she keeps telling me she just wants to take a proper break for a few months and start afresh, and see/talk to each other less. We no longer work together, I graduated in May and was offered a position I couldn't refuse, a professor I had worked with during my final year had an opening for a PhD and wanted to offer it to me before advertising it, so I accepted it and have been snowed under with work for the past month, not getting home til after 8pm some evenings, I have enough on my plate with this at the minute.

I know I'd be silly to stay in this relationship, but I would be grateful for some of your views on the issue.

Thanks a million
