Educating the clueless father so he understands what I'm going through physically and emotionally...HELP?!

Ali
Does anyone else feel unbelievably alone during their pregnancy? The other day my man was certain he would know the sex of our baby after our FIRST ultrasound... He has absolutely NO clue what is going on inside my body and I don't think he cares to figure it out. It is extremely annoying and also makes me feel so alone knowing that he has absolutely no idea how a baby develops. I don't want to be mean and tell him to pick up a book and educate himself, but what other option do I have?! It blows my mind that he literally has no clue what is going on. What should I do???
