Frozen,
I am not one to blame alcohol for all the troubles of the world. Some men are jerks and some are jerks that drink, I have been married for 20 years and my husband is an alcoholic. He has not cheated on me or run off in a fit of midlife crisis. And if he did...I would tell him to enjoy his new life.
Have you looked into Alanon? There is alot of good reading around here too.
Welcome...make yourself at home.
Hugs,
JT
