How about pausing the mortgage payments now to help fund the separate accommodation for your spouse. That would give breathing space while the divorce proceeds.
Ultimately consider selling the family home, you living where you job is so you only have one household and your spouse in her new location. The adult children will be away in college, they may need to get loans and jobs etc to fund their college life. Pay off the mortgage, split the assets and move on with your separate lives.
I really sympathise, divorce is hard, but one household will have to split into too somehow. With the house sold, the mortgage paid off will there be enough left to put down payments on new homes? You will probably both need to get a mortgage.
