How do you heal when you’re the screw up?

I love my girlfriend like crazy, but I’ve been unfaithful for the past few months. She was a good girlfriend for the most part, but I was always concerned about her behaviour. I always felt like she was the one cheating on me.

She was rarely interested sex, she seemed flirty was other guys, had too many guy friends, and used to brag that her guy friends wanna fuck her. This so mind boggling I lost sleep over this. I was convinced that she’s cheating on me. So I started having an affair myself. I’ve been having affair with another woman for 5 months now. My girlfriend never caught me red handed but she had her suspicions and left. Now I’m feeling lonely, down, and extremely depressed.

I know I’m the one at fault here, but how do I get over her?
