I'm not catholic and we believe in the same God and read slightly different bibles. Either accept me as I am or find someone who is catholic if that is relaly important to you but please don't try to convert me. If the few odd differences in our beliefs is the only thing that makes you want to leave me then we aren't right for each other and we should be trying to make things work out. We're better off as good friends.
A little context. At the time I thought that we could work out the few differences we had concerning religious beliefs and still follow our own beliefs while continuing our relationship. I didn't realize that she felt differently and that me not completely converting was a deal breaker for her even though she didn't say it until after a year in. So yeah that's what I'd tell her. I'm glad I learned something from that experience and hope to use what I learned in the future.
