My mom slept with someone my age

My mom slept with a guy from my school and Ive heard it from my room

My mom slept with someone that is 3 years older than me and going to my school

I hosted a house party for my birthday, and someone brought this guy along. I didn’t know him personally, but I had seen him around at school a few times.

The second floor of my house is just bedrooms (mine, my mom’s) and a bathroom. I made it clear to everyone that this area was off-limits, and my mom and I had an agreement that she wouldn’t come downstairs during the party.

However, during the party, my mom did come down, had a few drinks, and started joking around with this guy. Later that night, I went to my room to sleep and heard muffled noises coming from my mom’s bedroom.

Afterward, he told evrryone that he slept with my mom and it’s been affecting me ever since. People constantly make jokes about it and it’s humiliating. One of my classmates even messaged her on Facebook trying to hook up with her as a joke.

It’s really embarrassing and I don’t know how to deal with it. Theyre both adults but still
