Not sure about your ..backstory. Feeling as though I’ve regained some solid footing after a 30 year stint (and two children), I’m glad it ended. Set me free. The logistics of ‘finishing off’ my daughters was trying beyond description, but we survived.

Primates don’t appear to pair well for life. Tried my best, though ~

If it's about religion, you could try my own highly effective technique. Only give the person positive feedback..smiling, looking at them, listening to them, etc. when they are being kind, positive, and not talking about religion.

If they bring it up, look distracted and bored, mumble "Um-hum, that's nice," then immediately excuse yourself and walk off as though remembering something you have to do.

I trained my relatives to avoid attacking me in only two visits, using this technique.
Nobody likes being ignored.

Sorry
