what's the use of being married if this is lacking?
If that's your question, do you really need advice? I hate to go down the road of suggesting cheating or divorce, so I will just say that you seem to know what you need.
I am not quite in your situation, but I have a JW wife who misses me being a JW with her. We have occasions where something is wrong, but it really isn't like your situation. All I can say is that if you don't want to cheat or divorce, you need to change things at home. Marriage counseling is probably out. My JW wife would not go. But it really is the answer for whatever her problem is. After she won't go, a heart-to-heart conversation about cheating or divorcing because you know you won't stay in this situation indefinitely is about the only option left.
