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?

It’s human nature so there tends to be bias in the relationship. Can’t totally avoid it. Try to minimize contact and avoid doing things which mil doesn’t like, if possible. Just have to let it go at times and try not to be affected by the reasonable behavior. It is not worth it as your mil won’t be bothered and understand from your perspective. At the very least, u will still have your own mother and family to support you and fall back on during difficult times. :)
