My husband is threatening divorce. both of our names are on the deed, but only his name is on the mortgage. ?

I want to stay in the house, because my children live here full-time and attend school in the district. I would not qualify for the mortgage on my own. Would we be forced to sell the home, or could I possibly try and get financing with a co-signer and buy the home from my husband...or what do you recommend since my name is on the deed....not the mortgage.
