My partner (28) is suffering from a mental health crisis. Very low and talks about how he doesn't want to be here anymore. I'm very worried about him. He is refusing to speak to any friends or his parents about any of it. I am also struggling to cope support him on my own and feel isolated and like its too much responsibility. Is it ok to inform his Mother who he has a close relationship or is this controlling? We have had arguments about it where I have suggested I need to speak to his Mother if he doesn't. What shall I do?
