Well, hello there!
Welcome!
Why are you hiding the drinking from your partner? Just curious. Hiding the drink is one sign that maybe you have a problem. Have you looked around the site for other information that can help you answer your questions?
For me the drinking issue became very clear when I was blacking out and hiding the alcohol from my husband. It was also clear when I couldn't stop at just a couple anymore. I had to drink the whole bottle or whatever until it was gone reglardless of whatever state of mind I was entering.
Again welcome. I'm sure you will be very enlightened here!
