Was going to visit my ex-girlfriend - she was a freshman in college while i was a senior in high-school, and I had been selling my parents on this plan where I was “totally visiting so I could decide if the college was where I wanted to go - and I was totally staying at my girlfriends friend’s place, not her dorm.” Long story short, a mutual friend of ours went to her room so they could go to breakfast together where she walked in on my ex going down on a guy. So while I’m driving out I get a phone call where I was told by my friend that I should go back home. I didn’t. I walked in and confronted my ex about it, she tried to deny, while wearing a guys shirt that definitely didn’t belong to her. I left, stayed with my mutual friend for the weekend because I was embarrassed to go home and she was pissed at my ex for cheating. Weekend highlights also included a fight with the new guy my ex was with, which I’m not proud of, but such is life.
