I agree with this, I spent most of my pregnancy by myself and my husband spent the entire weekends socializing with his friends, hunting etc.
Meanwhile, I remember the moment I felt like I had gone back to the age of about 11 in my mind. I was insecure and needy etc. It was weird but I was fugging PREGNANT. Could I not be needy for a couple months? I hated him for being gone all the time and not wanting to spend his little free time to be with me, his pregnant wife. When you're pregnant things change and it sucks when you're the only one doing all the changing. I threw myself into hobbies...I even tried to start new hobbies to fill the time like you're supposed to like all those people say so your life doesn't revolve around someone else...but when you're pregnant you're carrying a baby you'd really like just for once in your life to really need someone, for them to be there and not complain or call you codependent, for them to do what they say they'll do, keep their promises, not be selfish, all of those things and not have them resent you for it. Looking back it was all very sad.
