I understand your question. I understand you would not be asking for anything other than a brief 'loan'. I cannot find any fault with that. In that respect, I would say you do as you feel best. I, of course, do not know the situation intimately, as you do.
2nd course-and this may just be spunky punkin talking-If there was any other way, anyone else to ask, even a bank for a small, short term loan through the holidays, I wouldn't give him the satisfaction of asking. Of being able to tell me No. Of saying yes, and feeling all warm and cuddly inside like he's Santa or your Savior or something.
Me personally, and again, this is just me, I'd rather take a side job on a street corner before asking my H for help.
Bottom line. You know him; who he is (was) and how he should react. I guess you have to follow your own best instincts.
Sorry, not much help, but that's my gut instinct. ((HUGS))
