Sandy, I can't speak for the OP but I know that with my STBXH I tried all of that and it made no difference whatsoever. Nothing. Nada.
When you're a normal, rational, kind person it's hard to believe that someone who supposedly loves you can possibly treat you with so little respect or kindness. You spend months wondering if your requests are unreasonable, or if you've asked wrong, or he hadn't understood. But eventually you're forced to conclude that you weren't unreasonable and you asked in perfectly legible language and he understood fine - he just didn't care enough to bother.
Let me give you an example. My STBXH refused for years to take on childcare responsibilities, despite the fact that we bith worked FT (and, not the it should matter, in fact I earned more than him). He was perfectly willing to watch me wake at 4 each morning to get a couple if hours work done before the DCs woke, because he didn't want to set his alarm earlier than 7. He'd then swan around taking a bath and getting dressed, while I did everything for the DCs. Often he's leave the house at 7:50 when our nanny arrived at 8, or even after she arrived. I begged him to take the morning shifts but for years he refused. Because he isn't a morning person. He knew I was on my knees with exhaustion, he knew my career was stalling, but he didn't care enough to wake up at 6:30 so I could go into work early and beat the rush hour.
Similar was true for every aspect of our lives. He just wouldn't put himself out marginally to make my life massively better. Housework, holidays, homework, school, socialising - all on his terms.
Sometimes he would do exactly what OP's H had done and agree to a change but then never actually implement it. That was the most frustrating of all.
When I was contemplating leaving, so many people asked if I realised how hard it would be, being a single mum to 3 young DCs. But the honest truth is that it's a hundred times easier than living with STBXH because I'm not constantly undermined, there's less work to do around the house, and I'm gradually letting go of the seething resentment he engendered in me.
