Obviously most quotes will be slightly paraphrased, but display the truth as I perceived it.

To make a long story short, I've had a co-worker that has also been a good friend for about a year now. We'll call her Bee. She's been dating a man for about 6-8 months now, and living with her pretty much the entire time they've been dating.

Last night, I went over to Bees house to bullshit as we often do on Friday nights (video games, weed, booze, anime, food, or all of the above) After she lets me in both of her daughters (4/5 and 7) started screaming that I was there, giving hugs, asking for me to do things for/with them, normal kid shit. So, making a little small talk with the girls (Oh Really? You'll have to ask your momma about that... You know, stuff like that, the generic response to excited kids), I make the way to my to Bees room, where we usually do most of our hanging.

I haven't even turned away from Bee or her kids, taken my jacket or messenger bag off, and Bee's boyfriend pops off from behind me,

"You just gonna walk in to someone's crib and not greet them? Seriously?"

Now, at first, I assume he's joking, but when I turn around he's seriously pissed. I scoff and start to take my messenger bag off and put it in the usual spot (I'm a bit ocd-ish at times), and say

"You saw me and saw I was saying hello to everyone. It's not like I was ignoring you
But you can say hello to me, you know."

More, what he said really pissed me off, because this isn't his place. His name ain't on the lease, his name ain't on the car, and he doednt pay 50% of any bills (except party favors)

After a few moments he replied "Nah" with a fucked up look on his face.

He proceeds to sit in the room when us for 1.5 hours, refusing to speak or acknowledge either of us for the majority of the night, unless it was his turn in rotation for weed, and then only sometimes, skipping some hits then acting pissy if we assumed he wanted skipped.. He pulls her off to smoke a cigarette, they talk for a sec, and then he returns. I go outside to smoke with Bee a d ask her if I should go. She says no, but I still end up leaving shortly afterwards cause I feel awkward af at this point.


So, AITA for not greeting my friends BF before her kids? Or not apologizing to the man who loves in but does not own the place for not paying him enough respect?
