Sorry if its a long one but I'm really struggling....
My husband has finally exploded and walked out of the family home leaving myself and 3 children. His mental health has been an issue from day one early life trauma, mum died young, absent dad etc etc. We have our eldest together then split just after she was born moved on we both had another child with new partners but eventually got back together 6 years ago as I always said he was my true love the one that got away! We had a son 5 years ago and married 3 years ago. Life was great so I thought ..... He has always suffered and in his rages tells me he never wanted the kids etc etc but I ignored it thinking he didn't mean it and carried on. He doesn't work as he can't cope with having a boss so helps mates out now n again for a bit of extra cash. His mental health went bad and He moved out for a break last year but after 12 days and a huge discussion he came back and things where implemented for him to have it easy as possible ie me taking over kids, cleaning shopping etc ... Great was fab for a few months then he started smoking more weed and I could see him spiraling down into this black hole. I arranged appointments with his doctors got him meds etc he then said they weren't what he needed etc so stopped taking them. My illness became worse and I've had to start chemotherapy orally to try sort me out ... Wow he sprung back helped loads all be it for 5 weeks but it was great my hubby was back so I thought! Arguing started he'd tell my son 11 (his step) he hated him etc he was the cause of the arguments between us both etc etc you get the jist... Well he finally erupted on his knees with a knife to his wrists I had to call police kids begged me luckily they never saw this they just heard his shouting pots crashing smashing etc... and walked out. We have messaged and I've found out just how low he is and I feel terrible as I've failed him as a wife but I'm so hurt he has no emotions, feelings etc ..... What do I do? I wanna help so bad I love the man!
