Well this happened a couple years ago but it still eats at me. 
It was 2017 and things were not going so great for me. I was laid off from a job and then denied my dream job. My best friend was always hanging out with his gf and her friends/family. He even got the gf’s friend a job with him while I’m struggling to find a decent job. My other roommate is hanging out with the rest of our friends and I’m stuck at home. 
Well an opportunity to move and help a family member came up and I took it immediately. I packed my things, said goodbye and left. I moved 1,000 miles away. I still paid rent every month till the end of our lease cause I couldn’t find anyone to fill my spot. I wasn’t that I hated my friends but I wasn’t happy and felt stuck. 
Skip ahead a couple years and I’m talking to my best friend and he’s still really fucking pissed at me. Said I put it on myself by not talking to him about it and just leaving.
TL;DR Moved out without telling roommates to get out of a rut. Still paid rent. Pissed my best friend off in doing so.
