So he's been telling you for months if not years that you don't matter, and he expects with a couple of texts that everything will be OK? Not only is he drinking, but he's practicing financial infidelity which is a whole other bag of beans.
At the moment, he's lovebombing you because you're not following the script. He's crapping daisies from his bum and giving you the bouquet.
If you google "Chumplady three channels" there's a post that you might find to be of some interest. It immediately came to mind when I read your thread.
