Tough subject because it sounds like your asking two separate things. I acted like your girlfriend acted when I drank and lost many relationships over it. However, I loved alcohol more than any of the men who left me and that was a choice I made. Most of them warned me ahead of time and I chose the alcohol. So, although you left she made her choice.
Do you have a problem? Only you know that. When I drank once I had ONE it was on.... No turning back!!!! I only drank maybe once a week but I could not moderate. I tried and tried.
So, I don't see you as a hypocrite at all and knowing the things I did when drinking you probably made the right choice by leaving.
