I have to agree with Suki. You can lay it out on the table but don't expect him to stop drinking. I've been there. I'm glad I had my say. It really helped me even though his response was that his drinking was none of my business. I know he heard me. It freed me to do what I need to do to take care of myself.
I have been stashing cash because I don't want a paper trail, I've copied all our personal papers and mailed them to in a safe place.
I've got an overnight bag packed (good for 2 days) stashed at my best friend's house. I even bought myself a new pair of pants and two tops to put in that bag.
I've made an appointment for a consultation with an attorney. I've not decided to leave yet. I may not. But I'm gonna know what my rights are and what to expect if I do leave and file for divorce.
My husband isn't physically abusive. He can get nasty mouthed when he's drinking and something isn't going is way. Mostly he just sits in the backyard and slugs beer.
