This isn't so much about my roommate but the Ukranian tinder chick he was seeing at the time (now they're married btw)

The second night she was over at the house, it was pretty late and I was playing PS4 upstairs thinking they were asleep. I hear her walk into the kitchen and sit down for 15 minutes. Then she comes up the stairs and sits next to me. I look over in disbelief at her and she is holding my roommates phone going through all of his social media.

I start asking her what she's doing with that, but she cuts me off with her thick Eastern European accent and says "Ok, I know I'm crazy, but who is this girl, and who is this?" She's going through messages on FB, snapchat, etc.

Then I hear my roommate wake up and start yelling, "WHERE THE FUCK IS MY PHONE?" This chick gets scared and runs into the upstairs bathroom. He comes up and I signal to the bathroom, and he goes over to it: "WHY THE FUCK DID YOU TAKE ME PHONE?"

A high-pitched shriek emerges "I DIDN'T! I SWEAR!" followed by "OPEN THIS GOD DAMN DOOR YOU CRAZY LOON" She says " NO! I'M USING THE BATHROOM!"
So naturally my roommate kicks the door off the hinges and finds her with two phones in her hand.

He took his phone out of her hand and walked away telling her to get the fuck out of the house. The next day, he shows me pictures of her bruised up all over that SHE sent to him as a sort of threat to not break up with her.

A year later, they're dysfunctionally married.
