TwinkleToeMatilda "OP He keeps threatening his life... someone who truly is contemplating things like this does not openly tell someone. At least it’s rare."
I am not sure where you are getting that from. I think it is very unrealistic to suggest that.
He may be lying, he may not, he may try something, he may not.
OP in your shoes I would insist on counselling for him for his mental health. He sounds very unstable and that is very unfair on you and your children.
We have a suicidal family member, it is fucking terrifying and you have my sympathy for all he is putting you through at the moment.
Whatever you decide to do long term I would do all you can to get him to face this mental health issue/suicidation.
Then, when he is in a better place, I would try and calmly try to decide what you want to do.
My husband has never (to my knowledge) been unfaithful, nor I to him. So I cannot quite imagine how I would feel. But I do think I would try and decide what is best for me. That might be staying together or breaking up.
What he did in sleeping with someone when drunk, was despicable. Then he kept it secret for 3 years, was that bad, or was it worse he told you and unburdened himself?
The last thing he has done is contact the woman and then tried to lie about it and then told you the truth. He doesn't seem to be able to keep a secret for any length of time. Is that a good or bad thing? I just do not know.
I guess for me the fact he told her is not a bad thing, even though you told him not to. It is a selfish thing from him but I don't think it is necessarily about getting stories straight. After all, he told you the truth in the end so what would be the point of the charade of lying about some aspect of it.
Do you now know the full story? I don't know. And I think what he has done ultimately is to destroy some of your trust. But I guess not all of it. He hasn't remortgaged the house from under you or ill treated your kids, I hope. So, hopefully, you can still trust him in some things.
Is it OK to stay with someone you don't trust in some things? Maybe it is. But it is your decision.
For the sake of both your sanitizes he needs counselling and maybe together you can rebuild trust but only if he can put your needs somewhere high! He is selfish, self serving and a bit secretive (quite bad at it really).
But in all honestly, I do think many people are like that. He must have good qualities and it really depends if the good outweighs the bad, to me.
So I hope you make your peace. With whichever way you go.
