Hi pureseeker,
You poor darling I feel for you so much. You have a new born baby this should be the most exciting time of both your lives. ( when your not exhausted!)
You two need to see a marriage guidance councillor asap. He is heading down a very dangerous road who knows what he has said to the other women its time to confront it in a safe environment where you have support from a professional person.
This is the time for him to step up support you and your baby and if he is serious about you and serious about being a Father he will agree to go.
Good Luck
