Alright so this just happened about an hour ago and I need some advice on what to do next. Skip to the end for TLDR.

Me and my roommate bring home 2 girls (both attractive) from the bar back to our apt. After some drinks and music/dancing, I take my girl (brunette) to my room and my roommate takes his girl (blonde) to his room. I get to doing my thing with brunette girl and I assume my roommate is doing the same with his girl.

About 30-40 mins later after me and my girl are done, she picks up her phone and starts panicking. She says her roommate texted her their “emergency code word” and that she needs to check on her. She starts to throw her clothes on and I’m like wtf is going on. I check my phone and see 2 missed calls (phone was on silent) from my roommate and then I open our group chat that we have and it turns out that his girl is on her period.

I’m like ok that sucks for him but not end of the world “emergency code word” causing by itself. But it turns out my roommate got head from the blonde girl, found out she on her period, got mad and basically tried to kick her out of our apt while I am with her friend. To make it worse he actually ended up leaving the girl alone in his room and leaves to go to a party/find another girl.

So blonde girl ends up in tears and is like why is your friend such a dick etc etc. Why would he do that just because I’m on my period blah blah blah. They get their stuff and leave but are pissed.

We have done this often where we bring 2 girls back with us and never had any issues like this. He said later in the group chat that he was mad because she “ruined his nut” so I guess he feels like she wasted his time by not telling him she was on her period earlier in the night.

Am I wrong for thinking this is extremely fucked up and selfish thing to do? If it had been the other way around I would have just went to sleep or waited for my roommate to finish and then see if he wanted to kick them out. She even gave him head it’s not like she left him with blue balls.

Let me know your thoughts.

TLDR: Me and roommate bring back 2 girls from bar. Roommate gets head from girl and finds out she is on her period and gets upset. He acts like a complete dick to the point where the girl cries and then leaves our apt with girl alone in his room. Both girls leave. Is this fucked up or am I tripping?

Update: Thanks for all the responses. I talked to my roommate. He does not believe he did anything wrong. No apology to me for leaving me stranded with an emotional girl on her period. When I asked why he had to leave he just said “I don’t have to stay with her” “I can leave if I want idgaf” and then got mad (lol) and slammed his door. I don’t argue with people or do shouting matches (with good friends or hoes) so that’s where it is at. Going to take the advice of not going out with him anymore. I’ve known this guy for 7+ years so he’s a childhood friend but I can’t go out with a guy that does shit like that. Have a good weekend boys.
