AITA for moving out of my apartment 2 weeks before christmas?

I (22M) live in an apartment with 5 other men in a college town apartment. 2 of the guys who i’ll call Travis (21M) and LLFF (19M) actually are on the lease while the four of us just pay our 1/6th of the rent. The office is aware of us, so we’re not doing anything not allowed. i’ve lived with them for probably 3 years now.

I barely spend any time in the apartment as i’m usually at class or work. the last year and a half actually i’ve had work that i have to travel sometimes for, so i’ll be out of the house for sometimes 3-4 days straight. Over these years that i’ve lived with them i haven’t had many issues with any of them. i’d actually consider most of them to be good friends. Most of the time im not even in the apartment so there’s no way for us to really argue. The one guy LLFF is a clean man. he’s apt to get upset when shit is not orderly in the house. My room is pretty dirty with clothes and whatnot, but he’s not in there so we’re usually square on that issue. He would always complain though if i came home drunk, brought a woman over, or brought any liquor or anything in the house. I’m not really mad at that but i’d try to avoid him.

My girlfriend ended up getting an apartment, so i was spending more time at her place to avoid him. A couple weeks ago in december, I had my college finals and this weekend event for kids from my old neighborhood at the same time, so i was studying in the apartment for about 3 days straight and then had to go this event for 3 days, before returning and taking both finals that monday. When i got back from my finals LLFF had just cleaned the house and started complaining about everything. after about 5 minutes i grab a beer and sit down at the table. He sees me do this, looks at the other roomate goes “bro…” and starts laughing. I didn’t know what was happening and figured they were making fun of me so i cussed him out and left. I realize this was probably unreasonable, but i’d had a long week and that was my first moment to relax.

Over the five days i was out, LLFF was making fun of me in the imessage groupchat for throwing a tantrum. I already pay my girl’s rent and stay there a lot of the time, so i figured i might as well just live there. i eventually texted back letting them know i was moving out and then got my shit and left. Everyone’s been blowing up my phone talking about how i’m leaving them out to dry and everything else right before christmas. The rent is a lot and there’s five of them so it’ll only be an extra few hundred a month.I said id pay rent for january to give them some time. they all say thats not enough and need me to pay rent until the end of the school year when the lease ends. These are good kids at the end of the day, even LLFF, so i don’t want to fuck their situation up, but i don’t think that’s gonna happen.

I know legally i don’t have to, but i feel like morally i have no responsibility to pay rent if i don’t want to live there.
