My mother in law is so bizarre. She always supports my husband even when it's obvious he's wrong and it makes me feel like the outsider in the family. It's very very frustrating and humiliating. What can I do?

To be honest, you really are an outsider in your mother-in-law's eyes. Maybe she's not that confident in your decisions and ideals. Let her get to know you more. If worse comes to worst then have a heart to heart talk with her and let her know that you are bothered by her attitude, clearly maybe you both have issues with one another.
