In a word, yes, and more than likely it IS true. It is the nature of the disease. You say yourself that he promises to get sober, do this or that, and never does it. Wouldn't that be lying?
Take some time and read thru this area of the forum and you'll likely answer many questions for yourself. You'll see a number of threads that involve an A acting exactly the same as yours has, and you'll begin to see that it's all about them and alcoholism and not about you.
Another great way to get educated about alcoholism and also get some real-world support is to check out Alanon.
Don't miss the stickies at the top of this page--a lot of good material there, too. Welcome to SR.
