Its an awful place to be in. While not entirely the same situation, i know loss.
For my case, there is a some background i wont publicly post at the moment... But in order to gain my sanity, i walked away. I moved out because in my wifes eyes i was a piece of trash in the gutter. I could not survive in what had become a hostile enviroment to me. By that move in the end i lost my wife of 16 years, real time with my kids, the house, the cars, the assets, every friend i had made from 10.
i too was suicidal, for me it was because i truly thought i gone over to satan and that i was no good. The pain of it all was almost too much one day... nuff said. I had literally zero help. It was a dark dark time.
But i learnt to deal with the losses, for me, one day without confrontation was worth more than a thousand with it. It is really hard to have the relationship you cherish so much go sour. My wife and i were best friends, we married when she was just 18, we played house and had babies. Until our baby boy almost died one night, we had never even spent one night apart in 10 years. Now it has turned to hate, she lashes me with spite equal to the love she once had. It still hurts if i let it come up.
but i have made a new life, with true friends, my kids and i get on great, i have a new wife who loves me more than i ever thought possible. You are in dark days sd-7. But dont do anything rash... please. Your kids will need to more than you know one day... be there for them. If you need to walk away to avoid doing yourself or anybody elsr harm, do it. you will look back in years to come with gladness in your heart. Every time my children and i have some good time, i am so glad i walked away and did not kill myself because that stupid religion made feel like a sack of shit and that my wife bought it.
hang in there.
