Input: I broke up with my exboyfriend last summer and we haven't kept in touch as we don't really share any friends and he goes to a different college than me in the same city. His brother goes to the same college as me and he's a few years older than us. My ex and his brother live together in a 2bdrm apartment.

Last night I was out with some of my friends and saw my ex's brother and we began to talk and catch up because it had been a while since we'd last seen each other. Anyway one thing led to another and I left with him to his place. After we hooked up I was getting ready to leave then my ex walked into the apartment. I just squeaked out a 'hi' and ran out.

Now I saw that my ex blocked me on social media (instagram, deleted me off facebook). AITA? It's not like I'm dating his brother it was just a one time thing, I currently don't regret it but I'm not sure if what I did was bad.
