I don’t know what to do anymore

I had a best friend of a decade/ roommate for the last few years. He’s always had mental health issues but never had a proper diagnosis when I was with him. I had to cut contact with him for some personal reasons and ended up blocking him on everything.

Since that happened he’s seemed to hit a mental break. Mutuals will send me posts of his where he talks about deities speaking directly to him, bible scriptures having hidden messages specifically for him, or celebrities writing songs about his life.

My fear is that the most recent post was of him having hallucinations of me following him around when I’ve been moved out of the city he lives in for months. I don’t know if he has access to it, but I know he owns a firearm, and I keep getting anxiety of him hunting me down even though to the best of my knowledge he doesn’t know where I am. He’s since made a post stating he was wrong and “apologizing”, but the whole thing was still scary regardless.

I sent a welfare check to his house, and even the officer called back to say he could tell something was off and saw my cause for concern, but didn’t think he was a danger to himself or others at the time. I just feel like that means I have to wait until he does do harm, and right now I’m pregnant, so I have more than just me to protect. I just want to feel safe in my home again. Any advice?
