What are my rights regarding the refinancing of the marital home after a divorce?

I think that you need to go and speak with an attorney in your area as soon as you can. You and your husband have equal rights and equal reponsibilities with regard to the house and the debt owed.  Now, money earned during a marriage is considered marital funds so you can not really make the argument that you paid the mortgage to your advantage only. Nor, though, can he force you to have to pay down the loan debt even if it is with marital funds.  But if you have already filed for divorce then a date certain in time has come where you can ow say that the funds that you are paying the mortgage with are separate property and that you should be entitled to a set off for that portion of his responsibility you are paying.  And if you chose to pay off the debt to allow him to refinance and get you off the mortgage (a big consideration here) then you can also agree that he owes you those monies in another way or as a set off to another marital asset (like relinquishing retirement rights)? You need a good negotiator.  And him an attorney too.  Good luck.
