I hate Church and still feel obligated to go

[PETE_ROSE]

Sorry to hear of the predicament you find yourself in, however I do believe that you are not alone in your situation.  I have a good friend whose story parallels yours in many aspects.  Before dropping the nuclear option on your wife and bringing strife into an otherwise wonderful marriage, I would suggest exploring other options with your spouse.  Although the bible tells us to not forsake the assembling of ourselves I would offer that fellowship with other Christians can be found in places other than church.  Taking a hiatus from teaching Sunday school and for that matter attending church could be an option.  Being open about your feelings with her and perhaps spending time together pursuing your other interests could be beneficial.
