Hi Kate. He is drinking. This is his life, and it's not going to change. You need to focus on what you want for your own future, and how you can get there. Please do not procreate with this man as having children with an addict is the most painful thing in the world. To see your children be hurt like that is like nothing you will ever experience.
He is saying all the things you want to hear b/c he likely can sense a change in you as you become stronger. He will likely try some different things to manipulate you in some manner as he sees this happening, as this is a threat to his lifestyle.
Hugs to you. You will know when you have had enough, you won't be able to tolerate it any longer.
Take care!
