This behaviour ended my marriage . My ex would behave in a really selfish way and I would ask drop small hints and ask, very gently and politely , for him to stop it. Then I'd wait patiently for years for him to change. Because he was so difficult about it.
Then once I actually sat him down and said that he had been promising to change x for years and he'd done nothing about it and I was really unhappy.
A few days later he came in on a Saturday night and said he was leaving " because that's what I wanted " . He had it all planned out and he'd found somewhere to stay . He tried to get me to sign paperwork there and then - about 5 minutes after he had told me.
So we separated immediately .
And then six months later he said " I didn't really mean it, it was just a game, I wanted to punish you for complaining about me. I wanted you to stare into the abyss and see how awful life would be without me. Now I feel you have suffered enough, I'm prepared to move back in " .
But of course, what had happened was that I'd had 6 months of realising how hard it was to live with someone who was 100% selfish and who took no acount of anyone else or their feelings. And I didn't want him back. I had moved through the shock and the grief , I'd been to cousellling and was enjoying having so much time to myself.
For him everything was black and white, it was " if you love me then yOu must be 100% happy with everything I do all the time " . The slightest complaint was the end of the world to him. I had no right to any opinions or feelings about anything.
It was no way to live.
