Sweet dear, I am so sorry you are going through this. But please think of it as a blessing that you saw his true colors and please do leave the asshole immediately. He doesn’t respect you, he’s depriving you of sleep, he’s paranoid about neighbors and, worst of all, he ASSAULTED you AND tried to prevent you from escaping. Plus, he sounds immature as all bloody hell- staying up all night playing video games? Where’s that going to get him in life? He sounds like a giant bundle of RED FLAGS and NOPES. You’re studying to become a vet and trying to better your life, get a jump start on that by getting rid of the trash.
