I'm sorry Mat. That is so unfair. I know that some of my friends have been through a divorce and the custodial parent was able to keep the house until the child graduated from high school. Upon graduation it was sold. Maybe this option could work for you. H could help you pay for everything involving house knowing that once D graduates it will be sold.
Life's challenges are not supposed to paralyze you, they're supposed to help you discover who you are. -- Bernice Johnson Reagon
