Try talking to your husband. He might be worried about what kind of father he'll be, how he can afford having a child, how his relationship with you, his wife, will change. These are not trivial issues for an expectant father. He might be having trouble talking about it and coping with it. Loss of freedom may not even be the real issue here. Look at this not as a problem but as an opportunity to connect with him.
Next Steps
Strengthen your support circle that may include friends, family and relatives.
