I want to cancel our adoption.
Why do you want to cancel the adoption?
My wife is the only one who's excited about this adoption
Even though it is disappointing to the child to cancel the adoption, if you don't feel comfortable about it is okay to cancel the adoption. Otherwise you might regret it if you go through with it.
How could my wife still be excited when she can't find her matching shoes!
Not everyone is ready to be a parent. You don't need to have everything figured out like her shoes but be open and willing to grow.
