Hi musiclady, sorry for you and your children of what you're going through.
I stopped drinking when my husband left and I looked at myself and I didn't like what I'd become. It wasn't a ploy to get my husband back but I really hated myself at that point.
It is different for all relationships though, I imagine. Have you seen the 'families and friends' forum, there are people there who have been through similar .
Whatever you decide we are here 24/7 if you want to vent or want someone to 'talk' to.
