I started writing a summary of the events that led me to this post, but it was pages long and it still wasn't "all the info" so I gave up and am posting this question anyway, knowing that I have not presented all the facts. But here's the briefest summary I can provide:

BM and DH have 50/50 physical custody. DH has 100% legal.

BM has a serious mental illness that leads to her being involuntarily committed to a mental health facility because she is a danger to herself and others. This has happened three times in the six years and two times while they were married. It's is happening presently (this is the third time since their divorce). Her illness is treatable, but it does require monitoring and medication and some self care. She can't binge drink and it's recommended she sleep 8-9 hours a night as lack of sleep exacerbates the illness. 

BM was released from the hospital yesterday. DH currently has temporary full custody and there is a family court meeting with a social worker next week, which BM and DH will have to attend. It's unknown if SD12 and SD7 will need to attend. We know this is not the final say as the judge also ordered private mediation after this appointment.

It is a condition of BM's custody, per the most recent CO, that she receive regular treatment for her mental illness and submit to bi-annual psychological evaluations to maintain 50/50 custody. Additionally, and I'll explain why this matters in a minute, DH pays BM roughly $5,000 a month in combination of alimony and child support. (Yes, I know.) She does not have to contribute even $1 to the girls' medical, educational, or extra-curricular costs -- DH pays for everything -- so that $5,000 is fully for her own household.

We have recently learned that BM canceled her insurance because she "could not afford it". (This was the first thing she cut. She did not try to get a job, or sell her car, or move to a less expensive home, or stop taking vacations or the like. She just decided she couldn't afford health insurance or out-of-pocket medical fees and canceled her insurance and doctor visits.) She has not been taking her medication or being monitored by a medical professional for at least 2 months but it could be longer. We don't know. 

In the past, DH has tried for full custody but because BM's illness is treatable, he's only been awarded extended temporary full custody while she got weekend visitation during treatment (which was miserable, because we had to do all the driving and she got both Sat and Sun for 4-6 hours, midday, so we couldn't do anything on the weekends with the girls) and once she was cleared by her psychiatrists, she was able to get 50/50 custody reestablished. 

And here we are. Again, again. 

Besides the list of issues her mental illness presents (this is the first time her "episode" occurred in front of the SDs, and the fact that she abandoned her pets in her home for at least two days... to the point GBM had to break into the house to take care of them because she wasn't coming back) I have the following questions:

• Has anyone ever heard of... or does anyone believe there is a possibility that... the fact that she states she "cannot afford health insurance" for only herself when she gets $5,000 a month will be considered in determining custody this time? Can this be seen as an inability to manage her own health and money and therefore a reason as to why she should not be allowed 50% custody? I feel it shows she is not of sound mind and has other priorities besides her own treatment. But can the way CS and alimony is spent ever be a factor in custody hearings? 
• BM hasn't had a job in a while (because she does not pay taxes and they garnish her wages so she refuses to work) and has been advised by her social worker to file for disability and begin collecting SSI. Again, her illness is entirely manageable (if only she'd choose to manage it!) and that was a factor in the last hearing, where BM got custody again. Can she have it both ways? She's too disabled to work (when she doesn't take her medication), but she's perfectly fine to parent (when she's taking her medication)? 
• Will her refusal to comply with the current CO be counted against her in any way? Or should we just expect a hand slap?

Again, I know I haven't presented all the facts and so it's hard to answer, but I'm just curious if these things have ever come up for anyone. I will try to finish the story of the events that led up to this next court meeting for anyone who is interested. I try not to leave my blogs up for too long though. 

Thank you for any info you have.
