Let's break it down: She is "in love" with Jehovah, and now, Jehovah is your rival for her affection.
So what do you do when Ricky Suavé/Jehovah is luring your woman away from you??
The answer to that depends on whether or not you feel the relationship is worth saving. If it is, then you have to win her back.
When was the last time you brought home flowers for her?
When was the last time you had a date night or a weekend away?
Has she ever expressed an interest in doing some activity with you? Something like taking dancing lessons, going on a nature walk, taking a cooking class together; could be anything really. The point is, surprise her with something like that.
Jehovah isn't going to do any of that for her. Jehovah makes promises that he ain't never gonna keep. Jehovah keeps asking her to do stuff for him, but he never makes good on his promises. He never surprises her with nice things. He's a fake.
Start by doing something really sweet that she wouldn't normally expect - make breakfast for her tomorrow, complete with some flowers from the garden in a vase. If she wants to know why, just say something like "I understand how stressful this has been for you. I don't want to argue with you. I just want to be the best husband I can be." If she still wants to go to the Meeting™, tell her that you support her desire to do that. Would she like to go to the farmer's market after the Meeting™? Or for a walk around a museum? Or to a neat little café? Or just surprise her...
It doesn't have to be expensive or a grand gesture... something simple like a trip to the beach or a nature walk. Just spend quality time together.
