I was brought up a Roman Catholic. My mum's mum and her ancestors on that side were all RC and my GG grandfather was very active in the Church. I went to RC schools and never once experienced the horrors that some have had. The priest at primary school was a lovely man, loved children, and my secondary school was a convent but I never met anything but lovely nuns - many with a sense of humour and a good understanding of teenage girls.
I had a break in my teens mostly cos I had other things to do on a Sunday but always regarded myself as RC. So when I married age 20 I assumed my DH would have no problem in getting married in an RC church. How wrong I was! He had been brought up Methodist but rejected it altogether in favour of Humanism - not that he knew anything about that other than it meant he didn't have to go to church! As a man marrying in the RC church he had to agree to bring up children as Catholics. He wouldn't agree. The priest amended the document he had to sign to say that he would give "serious consideration" to bringing up children as RC when the time came and that was accepted.
When children did come along I took them to church regularly, they were both baptised, made first communion and were confirmed. The elder went to an RC secondary school (though both went to non-denominational primaries). Once the girls reached late teens my DH objected to me going to Mass every Sunday as he said it interfered with our weekends, so I stopped going - and in true style, we never went anywhere or did anything different on Sundays!
Neither of them married in Church. It didn't overly bother me but I was somewhat miffed that my elder DD had her children christened in the C of E despite none of her DHs family ever going near a church of any kind. It felt like a betrayal from her.
I am pretty sure I believe in God. I will never know, of course. I haven't attended church for about 30 years but wouldn't say never in future.
