What if patching up is not possible and all attempts result in your husband getting offended more? Your mother would never apologize for her behavior and instead justify all what she had been doing. You clearly know and acknowledge who has been right, but would always expect your husband to budge.
Now … your husband does not try to stop you from meeting/calling your mother, but himself is least interested in calling/meeting her. At family occasions where encounters are unavoidable, he would just say salam and move away. He does not appreciate her coming to your house too often and says nothing more than salam when she visits.
