I am not sure if both of you or one of you lives in a fantasy land. How could you buy a house if you maxed out your credit cards? If you have no savings, how would you pay down payment and closing fees?

Does your daughter live with you and there’s no mother at all? What do you mean where would she live? Where would she live if you didn’t move in in the house your wife was renting?

Before you’ve met this woman you lived with a family. Whatever happened to that family after you moved in with this woman?

You don’t have to answer any of these questions but it sounds like there’s some stuff to look into
