Does your hu*****and work? If so, you have to force him save money. i remember you said in the other post he was very generous so he might not care too much about his finances.. He has already said he wish he could support you and your daughter then just ask him to take some action as well.
If you really want the house just take some loan from the bank and ask your hubby to pay the mortgage.
Lastly I heard pregnant ladies are moody. So adjust yourself well.
All the best.
