The mediation recently scheduled was voluntary. It's my ex's writing. With a card from the mediator.
As far as the sober living, I can be with my son all day after school. At least, that was my understanding? Would I need to modify my 50/50 split when I just leave over night? He's with my girlfriend, in our home, in his bed. Is it because i CANT be with him over night?
Thank you for responding.

Do you mean our current parenting plan? Yes, that was signed by a judge.
