<human>: Can you give me the gist of the text in a nutshell?

Overtime time I became quite the busy guy. I had just gotten out of the college of education, didn't snag a job, and have been long-term subbing all of this year. I coach 6th grade select basketball on the side, which has now ended. I also play competitive coed volleyball twice a week. I also weight lift and run during my free time to relieve stress and maintain health. On top of that I work a second job in the evening most days.

The relationship started off wonderfully and she seemed to be the "one." I could laugh, be goofy, and have a fun time with this girl. Then I became busy and our schedules didn't mix, so I ended up only seeing her once (maybe twice) a week. During the last few month of my relationship, I began seeking out (but never enacting) new girls. This happens every relationship I am in. I am happy and then all of a sudden I am seeking for something new. I never remain satisfied or content. This break-up doesn't feel right like the last one. I want to be the best person I can be, but I feel like I have to always be in that "improvement" stage otherwise it becomes boring. I want to be with her, but I feel as though I need to be the happy and content by myself first, I am just unsure how to do that...
<bot>: I want to be with this girl, but am not satisfied because of myself. How to I find satisfaction in life?
