I think it is best to tell her what your beliefs are as soon as possible.
If you hide your beliefs they will only come out later and the consequences could be dire.
If you are willing to accept that she is religious, she should accept that you are not that bothered.
It has been well documented on this forum that religion (amongst other things) can cause big problems if one partner does not accept the other's position.
Tell her what you feel and be strong about this.
Be truthful from the start![]()
