Financial question about divorce and remarriage

I divorced my wife and remarried shortly after.  The divorce decree said I had to sell the house and give her fifty percent of the profit.  I have lived in the house for over a year now and she still will not remove her items.  The divorce degree does say she can move at her discretion.  The problem, I can't sell the house because of all of her stuff.  I pay her 250. a month alimony.  She calls and asks if I will give her 50,000 and call it even, but still give her the alimony for the next three years.  My new wife and I have only been married two months.  She is finishing out her year as a teacher and will be moving here in May.  My ex doesn't want her here, but I can't sell the house with her stuff stacked to high heaven. There is about 110,000 equity in the house and it is worth around 300,000.  I would have to pay all realtor fees, get the house ready to sale, and continue paying alimony.  I need help deciding what would be the best financial decision for me and my new wife. Should I make her wait until the house is sold and continue to pay alimony or should I give her 50,000 and pay the alimony, what should I do?  I really need help, I don't want to be unfair, but I don't want to be screwed either.
