It does sound like you are asking for confirmation of what you are already thinking and no one can give you that except you and the Lord. Marriage is tough, raising happy, healthy children is tough and setting an example for them of how to deal with life is a valuable skill for anyone to learn. My suggestion would be pray about your marriage, but in the meantime, teach your son that dad is an individual and as such, has his own lessons to learn. Teach him to love, be tolerant, respectful and supportive while still taking care of himself and his own needs. Model for you son AND your husband healthy eating and don't keep junk food in the house. Good luck - I hope that you find the answers you need.
