Chin up Chrissy I'm the very last person that should be offering any advice, but it seems quite clear to me that your needs aren't being met. This is most likely why you're feeling empty. Same thing happened to me after my bout of increasing my sex frequency - except I didn't last 6 months! Great job!
Have you read The Five Love Languages?
I'm kind of curious as to why you marked a calendar though. It's just my p-o-v, but isn't that kind of "in his face"? I kept a private calendar for tracking purposes, but also chose to not reject while I was working on this.
