I also definitely don't want her raising my future children, though, and I'll be very clear about that. I am the same good faithful woman I always was, just on a different path than I ever expected, one full of insights and blessings I never knew could exist.
I grew away from mine as my husband then-boyfriend slowly grew closer to his Mormon faith. Our relationship is not perfect, not easy, but absolutely amazing.
Personally I have a rule that I will not enter a relationship with a believing Mormon. Having said this, there are several aspects of this particular religion that you need to be aware of as these will greatly affect how she will approach you and the relationship as a whole.
She will try to convert you.
