Eighteen months ago, I made the mistake of agreeing to share a San Francisco apartment with someone I just met (he was touring the unit with the real estate agent at the same time as me). He seemed quiet and unproblematic and had a good job/went to a top school (MIT) and I did made a point of having coffee with him with my partner and we both neglected to see any obvious warning signs (he also offered to pay a high rent for a small relatively undesirable bedroom).
**tldr: **It turns out he’s severely mentally ill, also very malicious and now planning to move into a new unit in the same building and likely end up torturing another roommate for a year.
For the first 8 months or so, things were fine. He was definitely weird (doesn’t bath/shower ever, just occasionally uses the apartment’s hottub, doesn’t use the kitchen at all ever, just orders delivery food and eats only in his room, doesn’t even use the living room, just comes in the house and goes in his room and shuts the door) but not overly problematic. I did meet his sister at one point who puled me aside and asked me to take down her number in case ‘anything was ever wrong’ with her brother
Then, one day, I came home and he was having a “psychotic break” or specifically what I would later learn was a “bipolar episode”. He was walking around the house talking to himself about nonsensical things, occasionally adjusting items in the house for no logical reason etc. He stayed up all night, played loud music on repeat at inappropropriate times and was clearly out of his element. At some point, I notified his sister about the bizarre behavior because I had no idea what was going on. She said he had a condition but didn’t specify much other than to assure me he wasn’t dangerous.
Days later, he finally calmed down and even apologized for his behavior and explained he was bi-polar. Unfortunately, weeks later he had another more severe episode, this one continued longer and even included purposely placing a sharp object on the floor in front of my door. I notified his sister again (she asked me to do so) which resulted in his father coming to monitor him for a day and eventually at the end of a day of baby-sitting him the father decided to call an ambulance and that resulted in him being placed on a 72 hour psychiatric hold. Apparently they had done this many times before.
Ever since that day, he’s hated my guts. He has been hostile, verbally abusive and extremely malicious (attempting to end any romantic relationships I have for no real reason other than he doesn’t like me). Due to the cost of the apartment and the lack of housing in my city (and lease obligation) it wasn’t practical to get out of the lease early, all I could do was avoid him as best I could, place a security camera inside my room to feel safe and mind my own business otherwise.
Now that we’re both moving out, he has decided to rent another unit in the building, and is now advertising for a new roommate. Because I’ve lived in the building for a while, I have the contact info for the condo owners of the unit he will be renting from. I am contemplating sending them a short concise warning about the man and to request that they notify any potential extra tenants (his new roommate) about the situation before renting to them. I want to do what I can to prevent the extremely unpleasant situation that happened to me from needlessly happening to another person. ** I think it’s unfair that the man does not disclose his medical condition to potential roommates despite the high likelihood that it will have a major impact on their lives.** The fact that he also tends to be malicious (there are plenty of perfectly nice people who suffer from bi-polar disorder) definitely makes things worse.
Does my thinking seem unreasonable to you? What do you think I should/shouldn’t do here?
