I used to wonder why parents would stay in bad relationships for the benefit of their children...then after having my own child, I would have walked through fire to protect her from a broken family! What I am saying is, I did not want to stay married to my ex, she was a clean freak and I was f tired of it. But I did want to do whatever it takes to make the marriage work for the sake of our child. Whatever I have to learn, I am ready to learn.
But my ex saw it different, she snapped her fingers and ended it, no marriage counseling, no trial separation, nothing, just end. There was no convincing her, it's like an iron curtain had slammed down. There was no one particular incident - no cheating, no substance abuse, gambling, fighting, etc
Sometimes in life you do not get any second chances, its just the end and you have to try and make the best of it.
