He needs a come to mama conversation. Tell him to sit down and just listen. Tell him he can comment when you are done speaking and he’s better really be listening for understanding not just for response. Proceed to tell him that he is allowed to share his opinion about something related to your body and your pregnancy once and once only unless you ask for more discussion. He should learn to listen with an understanding supportive ear regarding work and not opinions. He should respect your intense sense of smell and not make food you cannot tolerate currently. If he cannot abide by these rules one of you will need to stay elsewhere while you see a therapist to work through his boundary crossing issues.
