My mother-in-law is constantly comparing me to her other daughter-in-law. She warms up to her more than she does to me. The thing is, the other daughter-in-law is a giant suck-up, for lack of a nicer term. I have been myself because I feel it is inappropriate to act one way to someone and be completely different when they are not around, which is exactly what the other daughter-in-law is like. I haven't done anything to provoke the negativity from my mother-in-law. She is down right rude to me when we visit. And when the other one visits at the same time, I don't exist. I have tried to establish a relationship with my mother-in-law, but nothing works. What should I do in this situation? Should I approach her and discuss with her how much that hurts me? Or should I just get over it and face the truth that she will always ridicule me? I want to have a good relationship with her because she is my mother-in-law and I don't want to endure years of ridicule and comparison. Any adivce is greatly appreciated!
