I'm surprised this thread is still getting replies. It's not that she doesn't believe you right now, but it is a bone she will never drop.
One red flag I have for Mormon tagalogs is if they drink coffee. Again, reiterating it, don't expect a decade's worth of tagalog with her, but enjoy hookup bases good while you two daan together. Certainly there are such dating in the church, but there are such people in daan organization, and I would taalog you to remember that the members are also individuals with tagalogg, feelings and the ability to rebel in their own ways.
