It always surprises me when people express surprise at how divisive something like this can be. If you look at the top five things couples tend to argue about (I read years ago that they’re sex, money, kids, in-laws, and housework, btw), it’s the one that has the most direct and incessant impact on the quality of your time at home. I mean, yes, it doesn’t typically stir the sort of strong emotions that sex and money and conflict with/about other family members do…but none of those things colors every single hour you spend at home and awake. Housework does. And it’s relentless, even more so than having kids because you can send them to Grandma’s for a weekend every now and again. So yeah, it makes total sense to me that it can be such an issue.
As for the OP, I just don’t know what to say. If you’re truly committed to staying for the next four years, I’m not really seeing where your husband has any incentive whatsoever to change. You’re not going to leave, you’re not going to take his son out of the house, and you’re sure as shit not going to stop cleaning the things he won’t because you can’t stand to live like that. So what does he have to lose by maintaining his current habits? Bupkis, that’s what he has to lose. Not a single damn thing. Your choices, as I see them, are to continue as you’ve been doing, or to quit cleaning and let the place descend into utter squalor.
I have to admit, though I’m ashamed of the feeling, that I find threads like this something of a relief. I feel bad for the people who start them and am appalled by the behavior described in them…but they make me feel sooooo much better about my own inadequacies as a homemaker. I freely admit I’m not a particularly good housewife–the house is typically sanitary and reasonably straight, but it’s never spotless, I mow the yard and maintain the garden, but not to neighbors’ standards (to be fair, our neighbors mostly subscribe to the putting green school of lawn care), and it’s not uncommon for me to have to respond to his ritual “What ya been up to today, sweetheart?” with “Well, I mostly watched old movies, knitted, and argued with stupid people on the intarwebs. Oh, and I’ve not even begun to think about dinner.” When I get down on myself because I don’t contribute enough, it’s perversely comforting to know that there are people who are much, much less useful than me.
(In my own defense, I would like to add that I do have a part-time job to mitigate my financial drain, I make quilts and purses as a sideline, I make a lot of our Christmas presents, and the “old movies and knitting” days are mostly limited to the winter as I have the garden and preserving stuff from the farmer’s market to keep me busy in the warmer months.)
