As for the losing alimoney on cohabitation, even her lawyer told her that there was no reason in trying to fight that one. L said that for 20+ year marriages the "alimoney for life" was more doable. She has 8 years. First 2 at 100% then it graduates down from there. The 8th year she gets 10% of the original amount.
That is one of those things that varies from state to state. I was married 21 years and got alimony for life, same amount. But it ends if I remarry or cohabitate for more than one year, that is state law here.
