Erm, why does your husband expect to make life changing decisions such as accepting an offer on your house, without any regard or consideration for your thoughts and opinions? 
Especially as he does not plan on sharing the financial burden of such a decision. How does he get to opt out of paying his fair share of the cost of his child, his home and his living expenses? What if you decided to do the same? Your mortgage wouldn't get paid and your child would live in a cage at home while you work, presumably?
FYI, in 1998 I was still in high school. My living expenses have increased significantly since then...
My DH and I have a spreadsheet our living/household expenses. This includes everything, we don't bicker over what is mine, or his, and we each pay half into thus joint account for bills. We put some into our joint savings account and We then put what we each have left over into our joint spending account.
What each of us earn is irrelevant, and this will naturally fluctuate with payrises, mat leave etc, but the point is, we share the cost of living, and do so easily and happily because of marriage is a partnership of equals, an we care about, support, and love each other.
