Hi Gordie, Retirement funds are a bad idea because: 1. marital asset 2. penalty 3. adds to your income, so you will not only have an increased tax bill to the IRS, it could also change your support agreement, depending on how that's handled in your state.
I would consider personal loan, then borrowing from close friend as a last resort. Is there any way you can get an advance on your pay from your job?
Also, Andrew is right about the house sitting option being a good one. Do you know any realtors? Contact some. It's a pain to be in limbo,and have to potentially move more than once, but better than some other options you've outlined.
Also, while I'm thinking of that - what about something where you get a reduced rent in exchange for some work around the property? Again, contact realtors in your area or put an ad online.
Just some quick thoughts, hope they help. You're in my prayers and meditations. xoxoxo hugs
