T, sounds like you're handling a difficult situation well! I don't know how you take some of the stuff from your W, you must have a great amount of intestinal fortitude Regarding this part:
"States that she is forced to claim benefits while I live in a luxurious home. - Irrelvent, I'm stuck in this house with no other options available to me."
Let me offer this advice- if the house is a huge financial drain on you then get out of it ASAP. My brother got divorced about 8 years ago and kept the huge house and it became the biggest mistake of his life. He could have sold it at the time and broken even, but he was convinced he had a lot of equity in it that he needed that equity, so he was going to wait for the economy to improve. So he has scraped by month-after-month ever since barely covering his loan and bills. If his car breaks down, or the kids need dental work, etc. etc. then he has to borrow money or put even more debt on his soaring credit cards. So here he is 8 years later, and now he's spent another 288,000.00 (yes that number is correct) on house payments and STILL he has no equity!!! I have tried explaining the numbers to him but he is still clinging to the idea that his house will be worth a fortune some day and he can sell it and buy a smaller house and live off the rest. So he keeps throwing more money at the problem.
The only point I'm trying to make is if the house is causing your financial difficulties, take a lesson from my brother and cut your losses right away!! He stayed in his house because he thought he was punishing his W by doing so. Well she got the last laugh on that deal, he's stuck with a monster mortgage on a home that is constantly declining in value.
