My ex=hubbys parents were very religious, his Dad was a baptist preacher for 60 years, his wife was a preachers wife, to a tee.
They did not like me because I was Catholic, plain and simple. They ignorned me, talked around me and made me miserable. My ex was a Mama's boy, and would never speak up, he would just sit there with this dumb look on his face.
So, I stopped going to visit them,(they never visited us) he went on his own. Worked just fine for me and them, I never saw them again.
