People who walked in on their SO cheating, what did you do? How did you walk in on them?

So she had this advisor in her PHD candidate program. Its straight out of a romantic comedy or something. Dude is in his early 40's, handsome, British, went to Oxford, all the stereotypes. She was mid 20's, pretty, quirky kind of smart, and funny.

So while I worked 12+ hours a day to pay the bills, she was supposedly at school for 14 hours a day. She wasnt. No, apparently, she had a 5 hour period between classes most days that she came home to "study" with King Douche the Third. Be warned that he and I never got along, he always thought he was better than me and never missed an opportunity to show off his big brain.

So I come home early after a power outage sent all of us home. I walk in and there is Dr Who plowing my girlfriend over the edge of the couch.

I calmly shouted "What in the fuck is going on?", they scattered. Lord Cornwallis tried to sneak out but I grabbed him by the arm and escorted him to the couch where my girlfriend was sitting and made them explain. She said it was because I was gone all the time, and that he was there. He made this smug expression and told me that "she needed a real man around, someone who was on her level". When I asked for clarification, this dick head has the nerve to say "She is a PHD candidate, you're a blue collar worker who has no ambition in life. She deserves better than you" and does this Simon Cowell I'm better than you look.

He goes to stand up, puts on his clothes and when he passed me, he did this huff thing like you do when you are trying to non verbally communicate that they are assholes and I lost it. I grabbed him by the collar of his shirt, threw him on the ground, and proceeded to give him an ass kicking George Washington would've been proud of.

I left him with the warning that if I ever saw him again, I would kill him. That there would be no ass kicking, but a rusty bowie knife to the stomach so that he would die a slow and painful death.

Last I heard, he moved back to England with my ex shortly after that.
