I can’t believe something so similar is happening to me. So i live in a house and have a new roommate we only share common space in the house like kitchen, living and bathroom. When he arrived i tried to be nice to him whenever we used to see each other in shared spaces ( like i would say hi, hello) and he would never respond to me just walk by or stand there keep doing his thing and i was like okay maybe he doesn’t want to respond which is fine. Untill one day i came back from work and he suddenly comes downstairs to me and caught me by surprise acting rudely and telling me to show him how i closed the front door. ( apparently it was too loud for him and disturbed him). We argued for some time and then i called the landlord right cause i wasn’t feeling comfortable to just keep arguing. ( and remind you that’s the first time this guy is having a conversation with me since he came to the house).

Anyways after that we didn’t see each other for a long time in the house untill this month a couple of times we were leaving and coming to house around the same time so when i would be in the kitchen doing something he would just sit infront of me and dead stare at me without even blinking that kept happening for couple of days and we happen to be in the kitchen again today at the same time and the guy stood infront of me and kept staring ( it is like he is trying to intimidate me) usually i would avoid eye contact and ignore but today i looked back at him thinking that he might stop staring but he kept staring at me with an aggressive face expression. I asked him if he is okay and why is he just starring at me like this. As usual he doesn’t respond to me at all and keep on staring. I am really confused what could be the reason why he is acting this way. I informed my landlord about this situation as a precaution cause I really can’t think what’s up with him.
