I've had many of "those" conversations with my DH in the last 20 years and he seems to listedn and agree to do more, but nothing changes.
I realised that really I had been doing almost everything in the house/garden and the rest for most of our 53 years together. As well as a full-time, demanding job and even a part-time self-employed role at the same time. Now he's disabled, getting worse by the day - and ignores all the advice from the medics/me/internet about exercise and diet, and isn't really capable of contributing to our life any more.
We do watch TV together, and we do go on holidays (might be impossible in the future) IF I do all the organsing/packing/planning. Yes, he's a decent man to the outside world, but not to me.
As for any physical relationship, he moved out of our bed about 35 years ago, purportedly because I snored, and never came back. No discussion, no evidence of him missing me, no mention since (though I have questioned him about it). Funny, but we do holiday together (but all planned and executed by me) and he declares I no longer snore!
I am not divorcing him (should have done so years ago) but I do have my own hobbies and interests, some of which he does come to even though he contributes nothing.
It's unsatisfactory, but it's my choice for now. If/when he is bedbound I might re-think - but at my age I will probably stick it out.
Oh, it wouldn't bother him if I didn't cook/clean/wash and iron/tidy up - he would just live like a pig. If we aren't going out anywhere he doesn't even comb his hair, never mind shower. And no he isn't depressed, just bone idle.
