I don't practice in your state, but as a general matter, that personal guarantee probably would not be severed because of a divorce, unless that was written into the document.
One thing you might think about doing is getting someone from his side of the family to step in and guarantee *your guarantee*, but that would probably come at some cost negotiation-wise from your soon to be ex.
Lots of luck.
