I can't believe I'm writing this, but enough is enough. My DP is currently suffering from very serious depression and is suicidal due to lots of problems within his family (ill step-father and sister) but he is refusing to get help. This came to light about 2 months ago and since then he has tried to take his life twice, no one else knows about this apart from me and an ex-colleague of ours (we all worked together but me and ex-colleague have left recently) who I confided in as she also suffers depression. At first I thought I was coping quite well, I read a very good self-help book and initially thought DP was making progress, he had cut down on his drinking and improved his eating habits. However in the last couple of weeks his behaviour towards me and mood swings have become out of control. He is constantly accusing me of cheating on him and lying (neither of which I have done) and it's getting to the point where I'm scared to say anything, even ask something as simple as 'what would you like for dinner?', in case he suddenly gets angry and we get into yet another vicious argument. I know he is only doing all this because the monster that is depression has taken over his body, and I love him more than I have ever loved anybody else, but if he continues to refuse to get help I can't carry on like this any more. If I leave him though I know he's going to do something stupid and try to kill himself again, this time possibly succeeding because I'm not there to stop him. At the minute if he's not at work he is with me (I'm not currently working) so never has the chance to try anything but if I leave him he will be alone for the 15 hours a day he isn't at work. What on earth do I do? I can't cope any longer if he carries on refusing to get help, but if I leave I'll be responsible for his death and could never live with myself.
