My girlfriend and I got into a hypothetical the other day and I wanted to know what y'all think.

I was raised not very religious at all. My folks are Jain but kinda practice Hinduism and kinda practice nothing sometimes. Jain is basically similar to Buddhism in that at its core it's more of a way of life than a belief in a specific god. Right now, I am not religious at all and I don't really care about it one way or another.

My girlfriend was raised Catholic, her entire family are fairly religious but it has definitely been way less. They used to go to church but no more, but still believe. She is strongly atheist and rejects her upbringing. She has strong views about religion. Additionally, she would often tell me that she is jealous of other people who still believe because "it must be nice knowing that there is something waiting for you/there is a heaven to go to/etc."

We were talking the other day, and I said that if she were religious and it mattered to her if I were religious (but not strictly Catholic or Christian, just that I believed in something) that I would pretend to still be Jain. She said that is not right because it is important to her and that I shouldn't lie to her about that. I said that I don't care about religion only about her, and since it's not important to me I didn't think lying about it mattered. Additionally, like I said before, Jainism is more of a lifestyle than praying to god so it wouldn't really change much about me or what I do day to day.

So, what do you guys think? WIBTA if I told her I was Jain in this hypothetical situation? (Also, sorry if there are any grammar errors as English is not my first language.)
