doubleAries,
I swear my exBPDH, who is a truck driver, will be driving late at night and get triggered by a Billboard screaming for Father's rights, a radio call in talk show host, talking to a 'friend'- ... . You never know. It sounds like your stbx is somewhat isolated from others due to his illness and bizarre behavior. I hope the sameness of what he is exposed to every day helps to keep his extinction burst within some predictable range.
I am sure by now, you have learned to see the signs when he is starting to spiral. It is a waiting game, and so far, pretty darn good.
I would hire the attorney. You mentioned $75 for his last bit of advice which would have cost me at least $425 I am sure. My bipolar boss is always trying to do his own legal work. He rewrites contracts, enters into agreements without attorneys reading them, handshake distribution deals... . When they go bad, he ultimately has to hire attorneys... . which cost him a lot more than if he had just paid the few hours to review the contracts or make them as the case may be.
Just a cautionary tale.
It is so wild to read the beginning of this post to now. Lots of good things have been put into motion.
