For a marriage to work, both people need to put in the effort... if it gets lopsided too long, it is bound to fail. If she doesn't wake up and realize she needs to show you some real appreciation and not just criticize you, she's going to lose you.

Maybe you should teach her about the "compliment sandwich" which is to share something you LIKE about the thing/person, then a constructive, not destructive criticism, then another valid compliment.... makes the criticism easier to digest and process.
