Husband wont have intimacy

My husband and I have been married for 6yrs. We have a 11month old and im currently 16weeks pregnant. My husband won't take me on dates, nor do we have sex. last time we had sex was sept 15 around about. I feel like we no longer have a connection. When i try to talk to him about it. He either says he doesn't want to hear it or he's too busy. Should i stay or move on?
