Mom gave me a list of things that would result in my expulsion - marrying a divorced guy, marrying someone who wasn't RC were the top 2. So, I decided it was easier to remain single, although my sister married a non-Catholic and my brother married a divorcee. I checked with them, and neither had ever been issued the same ultimatums.
My Dad was a devout Catholic but his love for me was unconditional and would never have let that happen. One of the few times I ever saw him call out my Mom for her controlling attitude was in my defense.
After Dad died and we took away Mom's car keys, I'd take her to mass but when it was no longer possible for her to go, I never went back except for family funerals.
I will say that my mother devoted herself, heart and soul into her parish. She was always there, working, volunteering, cleaning, decorating. She was a parishioner there for over 50 years but when she died, only a handful of people could be bothered to attend her memorial mass. I remember getting into an argument with the priest when I went in to arrange her memorial mass. They kept trying to push readings from St Paul, and I refused to use them.
I'm just glad to have that aspect of my life OUT of my life.
