That all sounds like a mess I hope I never have to go through. I have known others through who upon divorce or separation, have voluntarily taken on the majority of debt just to get the unpleasantness done with as little fighting as necessary. It's not a fair solution but one that happens.
In the last few years, I have seen one couple I am close with go through an extremely messy and nasty divorce. It was pathetic - especially on one side of the relationship.
