Hello csips, and welcome!
The one truth I've learned over the years is that there is no amount of persuasion or motivation that I can provide to make my alcoholic loved ones change their behavior.
It is sad, but your bf is what he is at this moment. He is both the sober, wonderful him and the drunk him. If you can accept him as he is, then great! If not....perhaps it's time to let him go completely.
Changes to his behavior will come if and when he decides it's what he wants and wants it more than anything else. Change comes when the pain of staying the same is greater than the pain of changing. Change is real when the words match the actions--and actions are the most important thing.
