People that walked in on their SO having sex with another person how did you react? [Serious]

It's sad, I've had it happen 3 times. maybe its just me. =[

1 Was when I was 19 I was dating a girl who was becoming schizophrenic but not yet diagnosed. We got in some major fight because the drugs she used put her into psychotic episodes. We moved into an apartment together, she decided to celebrate with some drugs, we got into a full blow fight but made up, the next day I went to work and decided to come home early to find her fucking her old boyfriend (drug dealer), stoned out of her mind. I threatened to kill him with a knife, destroyed the apartment, and went to jail.

2 I was dating another girl for a little more then a year. She was having problems, divorce with military husband just finalized, her parents divorce, graduated college and moving without the support of her step dad. She was ready to drink the world. Well after a couple weeks of drinking way to hard. I couldn't keep up anymore, and let her go drinking without me. I got drunk ass dial at 2 in the morning, went to her friends house, found her drunk passed out, with her drinking buddy "older dude that had been trying to get with her for weeks". He was trying to have sex with her, not sure if he was ever successful though. I rolled him off picked her up and took her home. We ended things there but lived together, until we got her enrolled in her next degree program. When we were done dating I slept with all her hot friends, & she got jealous and wanted me back =P

3 Right after #2 I must of been such a pimp, fucking different girls every night of the week, in college. I went after a younger girl who i had been talking to on myspace and then Facebook for years. We started dating when I was still living with #2. Well fast forward a year into the relationship, the ex moved out, she moved in but hadn't fully given up my life of fucking around. I was never caught red handed but I was busted. We fought, made up, had sex, then the next day she was really nice fucked me again, then wanted to go to a party with her girlfriend. I agreed knowing shit might not be kosher, I had gps tracking on this bitch. she wasn't answering her phone, it showed she left the party just got to someone else's house. I followed it. when I got there 5 minutes behind them, I could hear her moaning from the front door. I banged on the door really hard, and some dude in a robe comes to the door. I push him out of my way, and walk in on her naked in his bed. Called her a fucking dirty ass whore and walk away. she follows me outside hitting and kicking me, I grab her arms she bites me. Eventually I left, and left her there to fuck him all she wanted.

-This was probably the worst memory of my life because I have to look at her every day, she is the mother of my son, and it sickens me every time I think of it.
