As an alcoholic myself and someone who put my wife and kids through a lot of the same BS, I would say that it did matter to me in the long run. I ignored most of it for years - and not because I didn't care - but because drinking was indeed more important to me at the time. It was all my fault and grossly selfish/ignorant/inconsiderate without question.
But I will tell you that the main motivator for me to finally quit was indeed what I was doing to my family. I don't know if I'll ever fully regain my wife's trust 100% and if I don't I accept that I probably don't deserve to.
