Is AUTHOR wrong in the post ? POST : This is kind of a long one so buckle up.

I live in residence at my university.
2 days ago my room mate approached me and asked if I would be willing to switch rooms with one of his friends down the hall. My room mate would get up at 7 each morning for class, and 2 nights out of the week I would come home late due to uni related events. He said it wasn’t anything personal, but that our schedules don’t match up and he wanted to live with his friend. I didn’t think much of it, and so I said yeah I’ll meet with the other room mate (I’ll call him K) and see what it’s like.

I chat with K who would become my new room mate, and he seems like a normal enough guy. Same faculty as me, all he mentioned was that he liked the windows open cause he didn’t do well with the cold. Fair enough. I tell my current roommate that it should be fine and I’m down to switch.

So the next day I meet the guy I’d be switching with (I’ll call him E). He seemed nice too, and we went about moving our clothes and bedsheets from one room to the other. Once we’re done moving everything, E says to me “oh by the way, K likes to sleep with a light on”. I was kind of surprised but figured he meant a small night light or something, but E had a blindfold so that was kind of sketching me out. I asked to borrow the blindfold just in case, but figured the light couldn’t have been that bad. I asked if there was anything else I should know and he said no, and so we went to sign the papers because at this point I figured there wasn’t anything too bad.

Fast forward to last night. I get back to my new room with K at about 12. I had a midterm the next day, so I wanted to get to sleep around 12:30. I asked him if I could shut the lights out to go to sleep, and he said he likes to keep his half of the room on while he stays up doing homework on his computer (why he needs lights on for his computer I’ll never know. The lights are also super bright-the entire room may as well be on). I was pretty taken aback, but didn’t want to start an argument the first night so I tried to sleep with my blindfold. It was impossible. And the window being closed made it boiling hot. To top it all off, he was on the phone with family at around 1 in the morning talking. I finally got to sleep at around 3 am when he went to sleep himself and I was able to talk him into turning the lights off.

I woke up at 7 AM the next morning to his alarm, which is totally fine, he has class. But he flicked on the lights. So now I was awake and not happy. I kept it together and asked what he was doing; long story short, he claims he absolutely needs the lights on to get dressed. At this point I’m aware I’m screwed and need my old room back, cause I’m now dealing with a room mate who;
- is up until 3 every night and wakes up at 7
-talks on the phone at 1 am
-doesn’t let me turn off the lights to go to sleep and wakes me up in the morning by turning them on 
-never opens the window and refuses to let me open it



A few hours later (couldn’t get back to sleep) I go to have a talk with E about switching back to my old room. I tell him that he didn’t disclose what the situation was like and I feel like I was put in an unfair situation. He said that he thinks he told me and that he also didn’t have time to tell me about it, which is definitely bs because it took like 40 minutes to switch our stuff around. I told him that I only switched because I thought my room mate wanted the switch, as that’s what I was told, and that he (E) purposefully withheld info and lied about his intentions to switch so that I’d agree. He denied this, and then said that it’s more my fault than his, because I didn’t ask (I did) and he isn’t really to blame here, and I am in the wrong.  That shocked me quite a bit and I couldn’t wrap my head around how he thinks I am in the wrong as opposed to himself, and he is now refusing to switch back rooms and I can’t do anything about it without his permission (I have tried). 

So, AITA for wanting to switch back into my old room, after the guy I switched with didn’t disclose what the room mate was like? 

Just trying to see if E is right and I’m actually being an asshole or if I’m correct in feeling he is.
