When a daughter-in-law gets a mother-in-law, it can be difficult to make the woman happy. The mother-in-law is your partner's mother, and her feelings should be respected. You can help her by being her friend and confidante. Become her gossip and share tips with her. Be her hairdresser or makeup artist. If you cannot do the laundry yourself, offer to help. Providing support is essential for a happy marriage..
