Hi! First of all, I dont think it will help you backing out or leaving your wife especially with your child under that circumstances. It will even add up to the feelings your child is currently having right now. What you need to do is talk to your wife and let her see and understand how important it is for your child to have her do that. Because eventually your child will really get affected by that. Like what the therapist or doctors said, its just a matter of behavior modifications. Eliminating some o fthe bad habits your son has through positve reinforcement or conditioning really helps a lot. Motivating and using some token if your child has done something good makes it even more effective. And also punishment is one form of behavior modification. If your child has done something wrong like in your case, then he deserves some punishment at certain degree. By doing this lets him think that what he is doing is not right thus optin him not to do that anymore. I think the both of you can do this if the both of you stand together.. You can do it! Just give trust a try... I will pray for you!
