I have a very big dilemma that i need help with to make sure that i am not in the wrong here, any advice would be much appreciated.

I have recently had a conversation with my girlfriend about our future and getting married. we have hit a pretty major snag because she is hellbent on getting married in a catholic church however i am not baptised and don't wish to be baptised at any point in my life, you need to be baptised in order to get married in a catholic church, i am very happy without religion in my life and don't intend on changing that at any point.

my question is, should i be the bigger person and just accept that i am gonna have to get baptised in order to marry the woman i love, or should i continue to refuse to get baptised for the sake of my core values and credibility.
