I do the same thing, except in an unpublished blog format. I haven't looked at it in awhile, and was surprised to find posts I wrote in 2009.. Posts where I complained about the same old stuff.. Him out drinking, him not working, him not helping me around the house or with our daughter, me and my hurt feelings, me and my anger, my sadness, my fear.. It has helped me realize that his drinking HAS progressed (as he continues to deny that he has a real problem). It has helped me realize that if I am foolish to wait another 5 years, my heart will be so broken that I won't even recognize myself.
I wish you the best, and the strength to do whatever you feel is the right decision for you.
