Your friend should speak to a domestic abuse charity, who will be able to advise her on reporting the partner to the police for controlling or coercive behaviour.
It's not really controlling just weired. Most other women would not stand for it but she lost her parents and a baby in quick succession, her best friend died of cancer and about the only other person she knows (other than me and the wife) has mental issues.. (50yr old woman lied down in tescos and was screaming on the floor)
He does not really tell her what she can or cannot do he just moans and complains and takes all the money!.. Up until recently she should it was ok!
