I never was a firm believer, even when studying there. I only went to please my parents. Same goes for going to Church afterwards, and joining a choir. But let me tell you how the Church itself gave me all reasons to quit:

Our old priest retired and was replaced by a younger one. The new priest immediately showed serious ego problems and antagonized a lot of people. When he went after the choir, I took upon myself to denounce his behavior to the archdiocese.

My reward? I was forced to apologize for "slandering" him. Since I refused, the choir severed all ties with me. Too bad for them, the priest still went after them and effectively shut down the choir.

After that I worked to help my mother, who by then had become the victim of a campaign of vilification from the priest (he read my parents' divorce papers during mass to expose her "adulterous" ways!). He handed us our best weapon though, when my mother eventually took a photo of him having an affair with a local woman.

After the priest was reassigned elsewhere, the choir attempted to get me back. I flatly refused. I had never had much interest in them to begin with, and they had to stab me in the back for trying to help them. I never went to Church again after that, and neither did the rest of my family (despite my parents still being religious – I guess they went the Anne Rice way).

Days spent apart from my fiancé because of DOMA: 1154 days, as of today.

And just like you, I ended up leaving the faith because SJ's taught me better than to be blindly obedient to dogma.
