Went through a bad break up

Basically was living with this woman for 2-3 months we both got jobs at the same place and we were doing fine then we started using drugs. She cheated on me multiple times with multiple different men, I cheated on her once I had an online affair with a woman I talk to online I told her she had to go I kicked her out of my life. Lots of name calling and unnecessary things were said, on both sides and the only regret I have was letting her move in with me and sharing a bed with her. Didn't know I was sleeping next to a monster every night and was completely blindsided. Don't regret removing her from my life if I had spent anymore of my time and energy on her I would have went full crazy. Also fucked myself up financially, I got myself a morning job and working towards finding a more permanent position. Things seem to be more normal now that she's out of my life.
