What advice would you give to someone (lets call him Bob) whose spouse (lets call her Betty) is mentally ill, and abusive. Betty is threatening suicide if Bob leaves her. She has a history of suicide attempts, some of which were clearly just attention seeking, but a couple of which were serious attempts. She has a diagnosed mental illness, a CPN etc.
The abuse isn't physical, but shouting, removing his phone, isolating him from friends and family, smashing dishes etc.
What help is there for Bob? He says that his GP has told him there is nothing available if the abusive partner is the wife, and the husband is the victim.
