Counseling........ really, seek it as a couple!
Your wife's 'trust' is clearly broken (as yours is too). She is needling you because she is angry. She needs some new coping skills.
Communication sounds like it is a s wrecked (geez thank you Mommy Borg).
50 days....... you should make a point to remedy that pretty quick, it might 'soften' her stance some toward you.... the longer it goes on, the more awkward things are going to get. You need to be her 'center', her 'rock'.........not the WTS.
If no counseling...... time to set an hour aside and set some 'terms' like you are only attending if she in return reviews the whole of the WTS (WTS material only). You are willing to trade your 'religious freedom' so long as she is willing to study an older publication too. Step up on you FWN position, infuse what you can and demand contextual discussion of all current publications. If she 'balks' at you spiritually taking the lead, drag out 1 Cor 11:3, Eph 5:22-24.....
>>>>>>> Remember <<<<<<<<
There is a small child involved and the court system is likely to give her full custody allowing you only every other weekend and all holidays. Which will give you precious little to influence her agains the WTS.
Lesson: Those who brown-nose the WTS/Elders/CO get slaps on the wrist, those who challenge are reserved for shunning hell...... it is a game, nothing more. You can choose to 'play the game' and get reinstated and than be very 'weak' or you can endure your place as fly on the wall. It is your choice.
