So sorry to hear that! What crap!
You know what they say about alcoholics. It's all quacking - quack, quack, quack. Just a bunch of b.s. hurtful, ridiculous nonsense.
I agree with suki. Alanon (and reading here) will really help you detach so that when he says and does cruel things you can just look at him and think, "Quack, quack, quack!"
Why would YOU want to stay with someone that says they drink and cheat because they don't want to be around you? Yuck-o!
You deserve love and respect. It doesn't sound like you are getting it!
Hugs and peace,
