At meal times, do you pray or does your wife say the family meal time prayer? Does she thank Jehovah for the food, that you provided? Does she ever directly thank you for all that you do for her and your children?
Do you or your wife pray with your children before bedtime? If it is your wife, what does she teach the children to pray about? Does she say the words "We are looking forward to the end of this system of things" and also "When all of Satan's system of things will be destroyed"? Because that would mean she is teaching your children to pray for your death and all the other 7.5 billion people on this earth that can't be politely bothered reading a Watchtower magazine and going cold calling to recruit so they can count 10 hours a month on their time sheet.
If she doesn't pray at all with the children that is fantastic.
I know it is an inconvenient truth for you right now because you are young with a small family to look after and you have an unbalanced, dysfunctional wife who really doesn't understand you. I am a stranger but from what you wrote I do not believe your wife loves and cherishes you at all.
She is victimizing you.
Having a 3 yer old child in bed with it's parents must be preventing you from having intimate closeness with one another. I think your wife likes it like that. Your wife has a track record of sleeping with other men. When are you intimate when you have a 1, 3 and 6 year old if not in the marital bed at night... But not when you have a child sleeping with you. Your wife would not be the first pioneer who used her "pioneering time" to seek and entertain her lover. If you are not being intimate with her, who is?
Wake up.
