I (26F) planned a full Friday–Sunday sleepover weekend with my two best friends because we aren’t in the same classes this term and haven’t seen each other much.

I ended up missing Friday because I had to go to the ER unexpectedly. She was upset, which I understand, but it wasn’t something I could control. I still came the next day. I couldn’t get there right when they wanted me to because I had a family dinner, but I showed up right after and brought a bunch of snacks, groceries, and face mask stuff for everyone.

While we were hanging out, one friend’s roommate (a guy) came home and wanted to join. Instead of ignoring him in his own house, I included him in Uno, Monopoly, and Pokémon games. It was all group setting stuff. I was just being friendly and social.

Later, my friend accused me of basically “cheating” on my boyfriend by talking to him and including him. For context, I had already told my boyfriend about the interaction and he didn’t care at all. There was zero flirting, just normal conversation in a group.

What bothers me is that this same friend has cheated in past relationships and has encouraged messy behavior before. She also tends to criticize my relationships because I haven’t been in a super long-term one like she has, even though hers isn’t exactly healthy from what she describes.

This isn’t the first time she’s blown up like this. About every 6 months there’s some issue where she gets upset that I’m not prioritizing her enough. If I spend time with my sister, go out with other friends, or don’t want to hang out after a long 7am–5pm class day, she acts like I’m rejecting her.

I feel like I’m allowed to have a life outside of her and be friendly to people in a shared living space without it being “disrespectful” or “cheating.”

So AIO for including her roommate in games and not dropping everything every time she wants to hang out?

AIO for being friendly to my friend’s roommate?
