This sounds like a very plausible explanation. many lapsed Catholics are like that, they can’t stand other people practicing the faith. My mother - while she was lapsed - would sometimes be annoyed by my regular church attendance and would use my new found faith to hurt me when I didn’t do things her way. She resorted to guilt trips and would bring up examples of my behaviour that was not consistent with my faith. And she was the one who was completely lapsed!
Anyway. Stand your ground. Don’t lose your cool and don’t get into arguments. Perhaps you could bring up the fact that she left the church that she promised to raise you in if she really insists on talking about hypocrisy. I think that we need to be kind but sometimes people just need to be reminded of a few facts. Who knows, maybe you standing up for your faith will help her return some day. You just never know.
