i would be very careful about your adoption plan..obviously he will be ok with it because it will absolve him of any responsibility. if i were you, i would maybe check into getting a certification of some kind while you are pregnant, so that you can get a job after the baby is born..then you can...
i am so sorry!
it takes a really big man to leave his wife while shes pregnant!
i would get every bit of money from him while you can and use it to leave him after you recover from having the baby. i wouldnt even let him go to any of the appointments since hes too good to be there for you...
