I hear ya and I feel ya @Shameless989 I have always done everything. Just fell into that trap - been married nearly 30 years.., Did 90% of the childcare, and the shopping, cooking, cleaning, washing, grunt work, life admin, and always everything at Christmas.
My 2 female adult DC sent me a notice of the internet the other day that said...
...growing up and realising all along that the Christmas magic you were always in awe of, was really just a mum who loved you very very much working hard in the background quietly, to make sure things were magical...
I showed DH and said 'awww isn't that sweet?'
He sulked for a few minutes, and said 'anyone would think they preferred you to me.' 

I said 'oh do grow up! They say this/think this because it WAS me doing every-fucking-thing, while you were sat on your arse watching TV, out partaking in your hobbies, or out with your mates.'
Yep men may not be arsed with the kids when they're little, but it does bite them in the arse later on, when the kids are much closer to their mums!
tl;dr not much help - and I don't think there is much you can do about it, as this behaviour has been pretty much set in stone by you. But your DH will regret it later on.
