I am.I am not familiar with a single healthy marriage where the man follows the woman to her chosen church...
The point is that you should work this out with your wife instead of taking up sides. If your wife gets something important from this other church, then you need to seriously consider continuing there for her benefit. Most of all, you need to figure out what she is getting there that is important to her....instead of the church the man chooses for the family.
This is not about getting one's way - this is about serving each other.
