The LDS Church meets many of the criteria for cult behavior. My wife and her family are a waants example of this.
I am married to an ER doc and agree that having your own life, being independent, and not going into the relationship with any preconceived notions is what makes it work for us.
She is now cl_interp_ratio 2 matchmaking with her uber-Mormon boyfriend and I am happily dating other people as well.
Some of tp family approves of my marriage and some does not.
