JIMMY- I think your wife's going to the elders is a means to an end of accomplishing something else. Something not even dealing with WHAT you did before you were married. I think your wife is trying to push the point of falling in line with the WT societies organization and she is " using " the alleged " guilt " she feels as a whipping stick to make you fall into line with the program in order to get you " back " into the witnesses. It's like she's grasping at straws , anything, to make you conform again.
It's a way to get you in front of the elders in order for them to counsel you. That's what she wants- in my opinion. I went through this over 10 years ago when I was still married to a witness wife ; and she called the elders on me because we had experimented a little with oral sex. She felt guilty- and called the elders without telling me. Long story short - my trust of her went out the window ( especially after she called my witness guy friends about going down on her reminding her of being molested as a girl ) and the marriage was doomed.
You have to make the decision you feel is best Jimmy- but remember your wife if she is a mind controlled witness is married to Jehovah- not you. And that's a fact that will never change as long as she is an active Jehovah's Witness. Just my take. My marriage to a witness woman did not work, perhaps yours may, but expect problems trying to make an undivided marriage work. Good luck with that
