Bert,
Welcome to you, this is a great place to vent or get some support.
My ex and I were just like you guys, we didn't drink during the week but on Friday after 5 it was time to party, then I just decided I had had enough, 150.00 a night down the drain, feel like crap the next day, only to do it again on Saturday night. My quitting did not go over well, it was like holding a mirror up to her face even though I never asked her to stop, only not to drive drunk.
The only way we communicated was if we were screaming at each other, she started beating on me because I decided to quit arguing, finally she cheated on me and left.
Do what you need to do for you, for your mental and physical health and for your future.
I hope you come back here often, and please think about counseling it was a huge help for me.
Best of luck,
Bill
