<human>: So I am going through some pretty rough times right now. I am currently in the midst of an unsuccesful job hunt while being heartbroken from my last relationship. 

During the relationship, all my friends kept telling me how lucky I was to be going out with my ex but we actually had lots of problems like communication issues and our personalities were quite different. I had wanted to break up many times before but each time I got too scared to break up and stopped myself. She really was a great girl and a great gf and I know I was incredibly lucky to have her but there were times where things just did not feel right even though she was such a great person.

Now that we have broken up I feel like it was completely my fault and I have just wasted three years of her life. I also really miss her and really really want her back :(. I feel like I will never find anyone else as great as her anymore and will be lonely till my death. So was just wondering if anyone have any advice for someone in my situation. Sorry for the long read.

Summarize the given text in a few sentences.
<bot>: Unsuccesful job hunt, broke up with great gf, miss her incredibly much and feel like will never find someone else again.
