Re: If one has a problem with their MIL…
I feel they should do whatever is necessary to gain control of emotions and keep behaving normally in front of spouse and inlaws. This might be talking it out with a trusted friend or family member who will not ever take the situation further or talk about it in turn to anyone else.
Sometimes people need to vent and let go of excess righteous emotion. This anger should not be bottled up inside if the person is going to begin showing resentment.
The ultimate motive is to make your own life as smooth and problem free as you can and to do whatever it takes which is in your own control to do so.
