Why do you want to have the baby adopted? I suggest you have the child and raise the child yourself. You should also seek help from your parents. Seems like the father of the baby is too young and immature. Don't bother telling him your plans, if possible.
My friend has this problem with her husband, they are not in a really good relationship right now and his husband is controlling her movements. She can still talk to friends over the phone but only for a short time and he listens to the conversations. He husband is also not giving her allowance...
