Brotherly Love
One time I was talking to a woman for a couple of weeks and we were pretty flirty, hanging out quite a bit, etc. It pretty clearly felt like we were heading towards a relationship. Then, in the middle of the night, she calls me, crying. She was at a party that my brother was at, and she made out with him.
Though she apologized for a ton, and I don’t blame my brother—he didn’t know about what had been going on with her—I instantly lost interest. The thought of kissing someone romantically who has kissed my brother romantically? Disgusting. Story Credit: Reddit/Worstgurl
