He gave me an ultimatum. tf

My “SO”and I have been in this thing for 12 years. No marriage. No children. However, we do live together....Fast Forward to last night, on a weekly basis my friends and i get together at a friends house for game night. It’s about 10-12 of us. About the only time i can wind down...And most times it runs super late bc we start at like 9pm. I try to leave or get home about 2ish. I work in the mornings and i do not miss work for anything. Anyways, he knows of this weekly event and around the average time i get home. Recently I’ve noticed that he will just call me in the middle of my outing wanting to argue about dumb shit or say something that could’ve just been a simple text. Or will start a convo, and then stop talking just so he can blow up the phone later like he’s “worried”and hasn’t heard from me...then last night he pulls that shit and I’m like fuck no. You’re purposely trying to ruin my night so i stop answering phone calls and text messages and we go play rock band...an hour later, i get back to my phone and he’s called me 9 times and sent me a text message asking where i was (he already knows) and that if i don’t get home by a certain time, he’s kicking me out of the house. I immediately flew off the handle bc that’s some manipulative shit. Meanwhile, on his “guys night” he doesn’t make it in until 5am sometimes. Am i overreacting? Or do i have a right to be pissed off? I don’t do ultimatums.
