I was a cheater

Hi, I have no idea if I'm in the right forum for this and on reddit I received a lot of abuse but... I was a serial cheater. I'm saying was because I stopped 2 months ago.

I am 21 years old and been with the man I love for just over 2 years. In October 3rd, I ended a 7 month long affair with an ex coworker. Before that, I previously had incidents with 4 other men that were short term/one offs. My boyfriend is aware and took me back thankfully.

But how can I forgive myself?
