@MissSunshine,
Try to figure out what you can let go, or delegate. Can you cook dinner in a slow cooker, get a babysitter sometimes, or have him wash the dog? Do the baseboards have to be dusted every other day, or can they wait two days? Can he take 90% of the responsibility for his own child?
Know what I mean?
And in the meantime, still, this is a communication issue. It definitely sounds as if you have gotten the short end of the stick. Your life has not improved with this marriage; instead, it's worsened. You need to explain that you are tired. And that the meals don't magically appear on the table. The children aren't bathed by an intruder who comes into the house for the sole purpose of putting them to bed. And clean clothes don't leap into his drawers.
You need help, you need it yesterday and no matter how much appreciation he is or isn't showing, that doesn't get the car serviced or the bills paid.
Recognize that this might just spur him to get you a housekeeper or a sitter, rather than help out.
