Art - I am sorry it is so upsetting for you. I don't think you can control the relationship between your husband and your son. If you decide not to be married anymore because of you and your husband's relationship/what you don't like about him - that is one thing. But to hinge it on the relationship he has with his son seems to me to be a bit misplaced. Would it be possible for you to listen to your son but not immediately jump to you having to act or try to fix it all the time?
