Different peoples have different opinions about religion. Well what I think is, no matter from what country anyone is and what religion they believe in. Their heart are the same as other peoples heart all around the world. There's no difference as we all are created by god.

Love is the union of two bodies & one soul ; two souls & one flesh. So I don't think its necessary to change religion for what you belong. If she loves you, why is there a question of religion?

Though religions are different, god is one. And no god allow voilence & war.
