If you get along with your 99, stay until your bb is born. I think your husband worries that no one will look after you when he is out of town. He puts you in the care of someone he trusts. You will feel better if you think this way.
We get very emotional and feel vulunerabel in pregnancy. So relax. Read baby-care books, do shopping for the babies, get some pretty clothes and listen to music at night. Meet with friends and feel special.
