I’m 19 and I was with my boyfriend (20) for a little over a year. I trusted him completely and never thought I’d be writing something like this. A few nights ago he told me he was staying at a friend’s apartment. Something felt off and I couldn’t sleep, so I ended up driving over even though I told myself I was being dramatic. I wasn’t. The apartment was unlocked. I knocked on the bedroom door and didn’t get an answer. I opened it and walked in on him in bed with another girl. I don’t want to go into details, but there was no misunderstanding. I froze. They both just stared at me. He said my name like I was the one doing something wrong. I left and sat in my car shaking for a long time. He didn’t follow me. He didn’t call. Hours later he texted me asking to explain. There’s nothing to explain. I found out later it had been going on for weeks. The same weeks he was telling me he loved me and talking about the future like everything was normal.

I broke up with him, but I feel embarrassed and sick and honestly kind of numb. I keep replaying opening that door in my head and I don’t know how to shut it off.

I just needed to get this off my chest.
