<human>: Can you condense the text into three sentences or less?

I woke up for work that morning to see her phone plugged into my desktop and the screen was on with a message from her sent right before we went to bed to this guy. I read through it a bit and found out it had been going on for at least a week. This was the last straw for me seeing as how she has done this six times over times throughout the course of our relationship. I know most of you are going to tell me I should have left after the first time, I know this, believe me but after having this time apart from her I don't regret it one bit. I had some amazing times with her, and plenty of fond memories that I will never forget.
I've broken off all contact and I don't miss her, not even a little. I think that after all this time of her making me feel guilty for her actions did it for me. It was easy to end it when she ended up making me feel disgusted to be seen with her. I just wanted to say that I had no idea I was depressed until I wasn't. Since this has happened my mood and attitude have improved beyond measure. I am myself again, and I fucking love me!
Has anyone else gone through a relationship this long and broken it off this easily and came out feeling like yourself v2.0? I've gotten a promotion and raise at work since that day. Women are noticing me that hadn't before, and I'm really enjoying the attention.
<bot>: Broke up with s/o of six years, due to non-stop cheating. No regret but not upset about it in the least.
