I have no idea about the legal aspects of all these things....BUT, since your Hubby has a diagnosed bi-polar disorder AND is medicated, AND has battled mania AND depression AND a Porn Addiction.....Can't these existing legitimate psychological problems be used to show that he is not a "good" Parent and should not be "controlling" the custody of your children??? He is NOT mentally fit. Or at least to show that there is incompetence and a lack of judgment on his part....also he is behaving erratically and cannot hold a job, much less is irresponsible with money? This WILL all affect your children...
To me, THIS should be your primary concern....and the primary justification and legal "defense" on your part. Talk about it with your attorney...
Your Ex does not seem like a well-balanced competent Parent. Being an "involved" parent is NOT the same as being a "good" or responsible Parent. He seems to lack good judgment and a sense of priorities. He does not seem stable, nor of sound mind.
I would be VERY hesitant to leave the majority of the custody to him. I would be nervous having my kids around him, if that were me. It seems like a dangerous situation. Why take a chance with your kids...when his sicknesses can forever impact them in negative ways. They are just children. They should not have to suffer for his manipulations and poor judgments.
His Porn addiction... that is something that CAN happen again. And, do you really know "for sure" that he is no longer doing that? With you getting divorced... he can very well do Porn again, since you are not in the house monitoring his every move. People like this are good at hiding it. And you have 3 girls? Yikes... not to be overly-cautious, but I would NOT want to have any child around that kind of mentality. And plus, his other psychological issues...
He is Dangerous for kids to be around perhaps? Can this be used as an "argument" and just cause for you having primary custody? Or perhaps, he can have custody WITH court appointed supervision....not supervision via "his" "involved" Parents. They will only protect him.... not your children or you.
He is a master manipulator...and can probably Bull_ _ _ _ his way through anything. YOU need to FIGHT against this, for the safety of your children. Sure, you want an uncontested divorce, but it is not going to be. You have to be even stronger and get a good defense against him... protect yourself and your children. Fight for them.
Document everything and anything... to build up your case.
Just some ideas. I really feel for you... pray, stay strong, and think of what is best for your children.... I know he is their father...but he does not seem very caring or stable. His behavioral problems will not doubt have an impact on your children and cause harm & damage them. They are too young to know any better.
Your Ex-husband is sick, and has ongoing mental problems. He can't even take care of himself and his family...how is he going to TRULY take care of children? You had YEARS of therapy with him...it has NOT changed anything. That is proof.
I hope you have a good Attorney who will fight tooth and nail for the safety of your children... and yourself. If it were me, I would not want my kids to be around him, or without COURT APPOINTED Supervision. But that is just me.
All the best,
