That is not a marriage, it is a weird partnership based on his desire to hored his money. I am curious what he does with the money he has spare. You should have both incomes go into a joint account and all expenses go out of that account. Expecting you to pay 50% of home improvements and vacation is absolutely absured. If he divorces you based on your financial problems then so be it. Any debt you have incurred will be spilt down the middle by the courts after he leaves.
