Backstory: my FI and I are both from Catholic families, and we received all our sacraments. On a base level, there's nothing impeding us from getting married in the Church. The tricky part is, when we met, FI had pretty much left the Church and was calling himself an agnostic. His father has pretty much ruined Catholicism and religion as a whole for him and his two brothers, by raising them their whole lives to believe that they're "not good enough" and that one sin = total anathema and a break with the Church. He stopped speaking to FI when he was in college and he skipped Mass to study for an exam. FI has been raised his whole life believing that he is "too sinful" for God to love, and if that's what God is, he doesn't want any part of Him.
After our PMI this weekend, FI told me that he realized how important marriage in the Church was to me, and that he realizes that I'm not just going through the motions, that my spirituality is really important and meaningful, and that he wants to give the faith another shot. I'm so happy to hear him say this, but I'm lost as to how I can help him without pushing or scaring him off again. Any advice at all would be welcome. TIA!
