I got a great idea, he can just move into the dorm room of his current squeeze, then her roommate can stay with OP. 
@JustOneDad these girls are from dorms that have separate bedrooms, I think.
Oh, so he has rich tastes…
Well, then, he’s definitely not following the rule that says you should use the best available facilities.
Except…I have to assume their roommates are girls, too and they can think about these things differently than guys.
This guy doesn’t seem to have too high of an opinion of it.
Why don’t you play the role of matchmaker and hook your roommate up exclusively with girls that have off campus apartments?
I am guessing OP is not attending BYU
So once in a while, say “Hey man, I can’t today. Why don’t you go to her place?”
This thread is gold.
Welcome to college.
Whats worse is when the girls DONT leave in the morning. They sleep even after my morning classes
Does he leave them in the room and go to class? IMO this is a no go. They could steal.
When I was in college I had a roommate who was never there and in a long term relationship. I guess they had a fight so she picked up a person our age but not in college. My roommate left him in the room several days! I think it was two or three. I was able to stay next door with my friends. My roommate stayed gone (back to boyfriend?) It was up to me to finally evict him and I drove him home to a trailer park. Yeah. I can hear all the other mothers here freaking out. He was definitely a druggie type. Roommate and I have not kept in touch. I have some epoch bad roommate stories and this isn’t the worst.
Uh, no he doesn’t. Sometimes he sleeps with him(just sleep!)
What an irresponsible roommate you had. Leaving him in that room without any instruction? How inconsiderate.
This is why I want to live alone off campus.
