<human>: So, me and the gf had plans to go out tonight. All's fine until I start to try out clothes to wear. I'm at ~170 pounds and have lost recently around 40 pounds. This is good and all but I still have major insecurities with my body. No matter what I tried, I looked myself in the mirror and got digusted by my own look. I'm working my ass off in the gym but my "love handles" don't go away.

Anyway, I get frustrated and slightly depressed. To the point where I even cried. Don't want to call it depression though. So, I know myself and being realistic knew that I wouldn't be going out because of my insecurities and because I was feeling really low. My gf at first was comprehensive but then turned and started to hurling accusations at me. "I can never do anything with you", "your selfish" etc. 

I felt like a cornered cat, she kept on escalating to the point where I burst. I tried to contain myself but I couldn't. This girl gets psycho and doesn't stop till things go to the extreme. She wouldn't stop and I resisted with all my might to punch her straight in the face. I did have to restrain her by putting her in a headlock. And before it got any further I left the house.

Who is in the wrong? Is it me for having these insecurities or is it her for not understanding me and my issues? I recognize that I'm no where as fat as I used to be but I have had weight issues all my life and they will not go away until I get to where I want to be.

Can you provide a brief overview of the text?
