Instead of being bitter about what you think you don't have, how about trying to be thankful of what you DO have? Some people can't have any children at all because they can't afford IVF or adoption. Nobody gets all of what they want in life. Be thankful for the daughter you DO have.
You can't afford more adoptions, so that should be off the table. And your husband has legitimate concerns about fostering kids. There are a lot of behavioral problems with most kids in these circumstances and bringing this into your daughter's life is a big deal. A couple must be on the same page, and both be willing to make the sacrifices necessary, when they choose to become foster parents.
I'd see a counselor to figure out how you can reframe some of your expectations and live a life that's more centered around gratitude than feelings of scarcity.
