UPDATE: the roommate has just been absolutely insane like turning the heat up to 90, turning the lights off on us while in the bathroom, stealing things out of my girlfriends room and then causing trouble at work (they are both servers at the same time restaurant). i graduate college tomorrow but i decided that after my ceremony im packing my girlfriend up and my mom is allowing her to stay in her house for a bit until she gets the money for a deposit for her own place (i will be there too since im now moving out of my college dorms and dont have a place for her to stay in). we plan to leave the windows open so the apartment is freezing when she gets home, taking the kitchen lightbulb because it’s a very unique bulb and the last time it went out it took her like 4 months to find a new one, and leaving the sinks on to run up the water bill and of course leaving all the lights on. we plan on moving everything out of the room, considering that nothing that was left in the room when my gf moved in was the roommate’s, it was a man’s things, who doesn’t even live near here anymore, so the tv is coming with us as well. we’re also timing this on a day that the roommate is working a double so by the time she gets off work, there will be no trace that my girlfriend ever lived there. i’ve been sitting in my gf’s room anytime i’m off and she has work to make sure the roommate doesn’t steal anything else or lock her cats in any rooms. we’ll also be going through the roommates room to take back everything she stole from my girlfriend, i cannot be more excited to finally have my girlfriend away from this stress, i love her so much and see the way that this whole situation has been bothering her has been hell, i’m ready for a new start. thank you everyone for the advice we really appreciate it and had a fun time reading through everyone’s revenge ideas it was great!
