I think you are jealous. It is Ok that your husband is good to her mother.
It sounds silly that you want to leave your husband unless you dont love your husband anymore.
Be nice & generous, your son or your daughter will do the same to you as your husband is a good example.
You can also nice to your mother-in-law, then you will not envy your mother-in-law anymore. Take it easy, relax and do behave like an adult ( a good wife, good mother and good daughter-in-law)
