As a wife who got taken for granted...I read what she says as a good thing, in some ways. She knows what she wants, she's telling you what she wants, and she is saying why she thinks you/her won't have it together. You just keep on being the best you that you can be - maybe she'll be convinced, maybe not...you'll be better off regardless. You won't convince her overnight.
Faith is, at one and the same time, absolutely necessary and altogether impossible. --Stanislaw Lem
