My sis is also having marriage issues but no kids. I hear it ALL as well and while I want to help her, no matter what I say doesn't help. She never takes our advice and I just end up just listening.
I agree to just be honest and keep telling her there's some things you don't want to hear. I was very emotional when I drank too so I know that doesn't help the situation.( sorry if she is saying it intentionally) The other suggestions were great and as much as I wish I could add, I'm not sure what it would be. I wish you the best and am giving you my support.
