If you think converting to please her is a good idea, it's not.
The JW life is a commitment to more than just going to the meetings. You will be expected to give up so much of your previous life (bad, good, or relatively harmless) just to meet this crazy standard that the Org expects of its members.
Passion fades with time, what is left over better be built on honesty and truthfulness. Going through outward motions just to achieve her as a prize will make you happy for a little while, but eventually, you are going to need something more in your life than "faking it".
