Do Amish courting couples ever breakup? Or does the bishop not allow that?
Occasionally a courtship will end instead of leading to marriage.
A bishop is the leader of the church, but not a dictator. He has nothing to do with whether or not courting couples break up.
Since Amish people shun modern things, what do they use for medicine. Do you have any natural remedies to share?
The Amish will go to a regular doctor when there is a need.
A lot of them do try natural remedies when they can. Some more successful than others. Several years ago I did a post of some of the remedies we used to use. You can read it here.
I've heard that Amish are often really young when they get married. How old were you?
I was 19 when we got married. Somehow that sounded a lot older to me at the time, than it does now. I have no regrets though that I was that young when we got married.
