I think many parents feel this way. I had a strict Irish Catholic upbringing & remember having many heated discussions with my mother about religion. She was adamant that I stick to ‘the Church’s teaching’ & ‘God’s laws’. She never strayed from the Church & expected the same from me. Like you say, I was expected to prioritise my relationship with Catholicism over my own beliefs & values. There was a period where I refused to go to Mass because I didn’t believe in practicing organised religion. My mother took this personally of course & got very upset. I only went back because the relationship between us was deteriorating & made me feel guilty.
Since my teenage years I knew that I didn’t want to get married or have kids. Of course my parents were very disappointed by this. They found it very difficult to accept that I DO have the right to choose my own path in life even if it’s different to the prescribed one.
