ok ok, I know technically it's nothing to do with me but....
ExP has been with his girlfriend for 6 months, 3 months of which she has been in hospital being treated for bi-polar
her dd doesn't live with her, she lives with her grandparents and I'm not sure what sort of access she has
ExP wants to move her in to his house so he can look after her and help her
he has been treated for bi-polar in the past but has been stable and off meds for the last 5 years
he has our dcs every other weekend
this set up makes me very very nervous
