Welcome, TD. You are absolutely in the right place. You're among friends - others whose lives have been affected by someone's drinking.
It's fairly typical for an alcoholic to blame someone - anyone - else for the problems going on around them. It's typical for them to start a fight or do whatever is necessary to deflect the attention away from themselves and their drinking.
Again, welcome to SR. Vent away! You might also want to take some time and read the stickies and other posts. There is much to learn about the disease of alcoholism, and how it can become a disease of relationships as well for us.
Hugs
