Short background: married 15 years. Kids broke her. While she had various diagnoses prior to us meeting including bipolar 1, after having kids she declined massively. She is thrice diagnosed BPD, bipolar 1 + 2, and a literal list of several other diagnoses. She disconnected from motherhood when they were around 3-4, opting to stay in her room most of the day. Marriage was 80% fine but the 20% was horrendous. Outbursts, instability in her own emotional state (and therefore in the household as downstream effect), classic BPD splitting on an almost quarterly basis, volatile nighttime routine when she handled one of our sons' bedtime, cheating, and general instability on a scale that was not clear when I was in it. She was always unwell and I enabled the shit out of it by doing everything for it and massaging my behavior and our childrens' to be palatable to her.

We're now divorced since mid last year. It started with a nearly-successful silver bullet attempt. I battled pro se with extensive documentation that prior to any hearings, we were able to work out a marital settlement agreement. She walked with 6 figures. I got full physical custody of the children with joint legal, and I have a tie breaker provision. She gets no overnights. in the past 6 months she's intermittently seen the children, totally about 45 hours (i track it) in that time. She does not work and claims to be seeking ssi disability

She has untreated BPD which has gone to levels that I have never witnessed. Recently I've found her social media. In a recent thread and ongoing posts that have gone viral she's defamed me at levels I've never expected. The account is anonymous to the extent she doesnt use her name, but she posts images of herself and of the children when she's in my home. via her social I'm seeing::
- she has an only fans (yes, I'm aware courts don't really care unless the kids are exposed to it)
- she's making public false false criminal claims against me that I physically and sexually abused her, drugged her at multiple points, conspired with others to do so, "probably" tried to kill her, among others
- openly seeks one off high risk sexual encounters
There's a lot more, but those are the highlights.

Weeks back, I caught her smoking marijuana while she had the kids in her care for less than an hour.

She ran out of the entire settlement last year. Stupidly, and seeking to be kind, I offered to buy her car (she doesn't need one as she doesn't go anywhere except to see the kids here, intermittently). She's running out of that.

I have been maintaining logs and summary of any engagement, and I have never denied her visitation or even asked to reschedule, even when she decides to push it off at the last minute. I always facilitate when she lets me know she wants to see them. The children are distancing themselves as time goes on. My youngest spent her entire last visit with me upstairs (i exit the floor when she's here)

She's likely going to face a financial crisis in the coming months. Alimony per our agreement is delayed until late 2026.

I am extremely concerned about her mental state. She is openly defaming me not just vaguely but with specific criminal accusations. She doesn't have the money to initiate legal action of any sort, but as we get closer to her running out of money, I'm concerned this could escalate into something drastic as she goes deeper into whatever psychosis this is.

I'm looking for advice from similarly situated men who have dealt with this sort of thing in the past. I keep good records, I have a recorder on my person running when she's here (i'm in a one party consent state) just in case. I am documenting her social media...also just in case. Notwithstanding the fact I'm not sure what "the worst" is, how do I plan for the worst?

And yes, I'm getting a legal consult soon to strategize and be prepared for escalation.
