Start looking for a new place to live.
Well currently you’d probably not be having guys over-since you’re not on a lease as you stated in your comments it would be best if you start searching for other living arrangements as even if you were to ignore him his sense of ownership and control over you is really disturbing.
Damn! That sucks but if you’re not gonna do anything extreme … you’re kind of in a tight spot. Unfortunately guys are salty and dicks when it comes to these kind of things. “I don’t want to be your friend so if you don’t want to date me then GFTO since I ain’t gonna be used” — kind of tight spot.
I was recommend just looking elsewhere — you want to be comfortable.
Otherwise you can always maybe sit him down and have a bro to bro talk — maybe you’ll get somewhere.
I’d be finding a new place to live soon.
You aren’t on the lease, he’s trying to only control you in the house and he tried kicking you out when he thought you were talking to someone else. You never dated him. Yet he’s acting like a jilted ex.
Makes me think about the women, Christina Scarr, who was killed by her jealous exroomate. She never dated him, he was obsessed over her, even put a tracking app on her phone and then killed her after she moved out in her new place(she stayed friends with him).
Secretly look for a new apartment and then once things are secured bounce as quickly as possible. You’ll need to move things quickly and discreetly as possible. If everything can be done in one day the better.
If he knows you’re looking he might try to talk you back in and if that doesnt work he might steal or do other things. Dont tell him your new address or anything. Break all contact after.
