Broke up with mormon girlfriend

We had been dating for about 7-8 months. She is an amazing person and really intelligent (I certainly can’t explain how she is still in that church, maybe her father being the bishop is the cause of it). At first religion wasn’t a problem, we still had a few conversations about it and she kind of accepted that I wouldn’t covert.

Last week she explicitily asked me to go to church with her, and and if I said no (which I did, in a polite way) she wouldn’t be able to share her life with me because I “would never get to fully know her”. I then realized my hopes of having a mixed relationship were in vain and that the best for both of us was to break up. After that, she gave me a book of mormon and told me to please read it.

I feel so sorry for her and that she is trapped in such emotional prison. We are still friends btw.

On her and her family’ side I was being rude for not accepting her invitation. However, I just find it so annoying that people try to “inject” religious beliefs into others. Is it that my atheist believes are less valuable that theirs? For the record, I never ever made her question her faith nor I asked her to skip a sacrament meeting. Of course I didn’t even asked her to have a glass of wine with me. Was I really being rude?
