<human>: A few months ago, I broke up with my now ex-gf of five years. We had been living together for 4 years. I felt that the relationship got to a point where I wasn't seeing her as a romantic partner anymore and I felt I needed space to work on myself. I was starting to experience some crippling anxiety and somewhat of a quarter-life crisis. 
  
So I ended things, moved out, got a new place, started a new job, made an appointment for therapy, etc. The problem is, a couple months have passed and I find myself feeling very alone and full of regret. That she was very kind and caring, intelligent and mature. It feels like there is no going back though, she said I am the biggest asshole in her book and I probably deserve that. I unfriended her on FB, and stopped following her on social media to keep my mind off of her, but I can't help but feel melancholy, especially as I spend this holiday weekend alone.  
  
How do I get past this? Has anyone else been in this type of situation? How did you deal with it? I don't really have a close friend base in the city I live in because I moved down here for work with my ex-gf and we were each others social circle.

Give me the gist of the text in a nutshell
<bot>: ended things with gf of 5 years, now experiencing loneliness and regret, but feel that there is no going back because she thinks I am an  asshole. How do I get past this and cope?
