Getting Divorced. Borrow money or raid my RRSP?

Hi, thanks in advance.

I am getting divorced and want to buy my husband out of his part of the house, which is completely paid off. He is willing to let me have it for around $70,000 which is around 40% of the value. Should I get a reverse morgage, line of credit or take from my RRSP This would represent aprox. 50% of what I have in there.

I live in Ontario and plan on staying here.

Many thanks.
