the worst roomate I ever had was the one who wanted me to break up with my girlfriend and move in with him into a two bed room apartment downtown, when he's still living with his mom. I'll never understand his intentions, and many of the people I told this story to, thought he was legit crazy, cuz that's an enormous undertaking for someone you've only known for 3 weeks.
Like when do I find out he doesn't clean his dishes? I was fortunate enough to find that out before then too. It's a long silly story.
So I guess the worst one I ever, was the one I never had? lol
