Sounds like you should make an attempt to save it, although with the knowledge that it may never happen. It sounds like he got hardcore shamed by church elders into leaving you behind (they probably gave him a serious guilt trip).

Ironically, I would say that you should do a hail-mary throw and tell him that you have strong romantic feelings for him and want to try dating him. If he says no, then that's that.

Good luck and here's hoping it all works out.
