Well life can be a sea of troubled waters at times. What i would like to say is that first her case isnt physical its a case that only God can handle. You should'nt throw her away because maraige is for better for worse. What you need is to really draw close to God. I've heard many similar testimonies and God easily tackled them. So now you must act like a man and stand before God so as to save the life of your wife and the future of your son. No matter what, you need your son and the boy needs both of you. Read mathew 11:28-30. Sucess, and God see you thru.
