WEll, Wendy - I'm going to play devil's advocate here for a minute.
First of all - what is your goal at the moment? To punish H for his unfaithfulness? To make him feel what it will be like to be divorced? Or to show him how nice it could be with the two of you, without OW?
Not judging any of these goals, just pointing out that your current behavior might not line up with your goals.
Then, the devil's advocate part - in your current situation, H's job is to go to work and bring home the income, your job is to take care of the homefront. I'm not judging or making any comments on SAH wives - I've been both in my time. I'm just saying that THAT is your current agreement, and your H might legitimately feel put out if he has to come home from work and do things like clean up dog barf and wipe down moldy furniture before he can relax.
Now, you can CHANGE that agreement. You can announce to H that you have taken a job and that from now on you will each be doing half the housework and half the cooking. That would be fair (and maybe not a bad idea, anyway, to start looking for a job for yourself).
Or, if you don't choose to do that yet, I would suggest you become a little more professional about how you approach your current job of home executive. There are good books and websites on the subject for those of us who are not naturally inclined (myself included). My favorite is this one: http://flylady.net/
Don't underestimate the importance of this stuff to your H, even if it doesn't really matter that much to you.
