I know already if it is not this woman, it is no other woman
The problem is that she does not feel the same.
Like any addict her first love is her religion. That will always ALWAYS come first. That WILL NOT CHANGE unless she leaves the JWs.
Like most people in a relationship with a JW you come second.
If she has children her religion/addiction will come first before the children.
Those are the terms of any addiction. If you can agree to live in her world and become a JW you will STILL COME SECOND.
You can't make an addict change. They have to do it themselves.
In the meantime, you need to make your life the best possible. It sounds to me like you are living with a lot of stress, a lot of giving in to her, and it never being enough.
And of course the life of any JW is that what you do is never enough. And that is what she is trying to push on you.
Hard decisions.
