Most Helpful Guy
For my last breakup... well, she cheated on me and I threw her out of the house. So I had a lot of anger over that. I used it in the gym and tried to improve myself. It worked well.
I also spent time with friends, and played a lot of video games. No contact with her. Out with friends, making new friends, flirting but never trying to take anyone home. Waited a few months, stuck to porn and good old left hand when I needed it, and didn't try to date until I wasn't angry anymore.
I felt, during that relationship, that she was making me pay for what other men had done to her. I was very afraid of taking my anger and hurt out on a new girlfriend, so I held off. Six months later I met the woman I married.
