Moving out?

So me and my bf have been living together for almost a year now and I’m pregnant I feel like things are going down hill for us he doesn’t really respect me anymore or listen to me I ask him not to do shit because I don’t like it and he agrees but then turns around and still does it behind my back so I was thinking maybe if I moved out and tried to distance myself away from him then maybe we’ll get better? That may sound stupid but who knows?
