Yesterday I broke up with my long term girlfriend, I had plenty of good reasons, some I told her and some I didn't. Since the moment I said goodbye I've had a deep, sick feeling in my stomach. I regret not trying harder, and I already miss her a lot. I can't even bring myself to take our pictures off instagram or take her @ out of my bios, and she hasn't either. I've wanted this for a long time now but I can't handle it like I thought I could. What do I do?
