Oh, and tell that jerk that you work as well as take care of the kids, and most of the housework. And that this isn't the 50's anymore. Tell him to hire a maid if he thinks that you're so "lazy".

Don't cook for him or do his laundry when he's that mean. If he's going to be mean, show him that you can be mean too. Tell him that you'll refuse to cook for him or do his laundry until he shows you some respect. Or you could just do one thing at a time.

The next time that he tries to ask you for sex, tell him that you're to tired to do anything after working all day then having to do X, Y, and Z, but if he only helped you out ab bit, then you'd have the energy for it, ha ha!

Sometimes you have to fight fire with fire.
