Inform her that you with it pursue the same aims therefore it is better for you to work not against each other and to rally the forces and to move together in one direction.
If your kind and straight talks after all did not bring any positive expected result, it is worth arriving in a different way. Cross through yourself and prove to the mother-in-law that actually you - not such and bad as it seems to her. Try to adapt to a situation as much as possible. Behave with her son as she would behave with him. Surround him with attention and care, constantly ask the councils concerning any given situation his mother. Ask it to teach you to prepare or to share with you other useful skills. Let she will feel irreplaceable.

Too get into its personal family records and the relations with the husband with the councils, try to prompt to it as it is correct to behave in any given situation. And it is necessary to do it accurately, but after all it is a little persuasive. Over time the curious mother-in-law has to understand the mistake and try to cease to interfere with your private life.
