Take the following with a grain of sal trot as I'm not a lawyer and don't even play one on tv:
As for support for your ex (I'm talking strictly about alimony here, not child support and not the division of assets acquired during the marriage): First of all, if she quit her job, alimony should be calculated on her presumed earning capacity, ie the income she was making at that job. You can't just arbitrarily quit your job to get a better settlement or to get out of child support. Second, in most states, it's standard to put in a clause that alimony stops if she cohabits with another man.
Third, debts or assets acquired after the formal separation date should be separate property.
