I am not a doctor. I am not a therapist. What I did learn over time: her drinking was taking a hefty toll on my emotional and spiritual livelihood. If your drinking is an issue in your relationship, you may have a drinking problem.
Alone, I am still somewhat of a hungry animal. I contemplate calling my recent ex more frequently than I'd like to imagine. It's a similar story to my previous relationship. Perhaps we can just get our physical needs met without worrying too much about the relationship or the future.
If drinking is a little like Ambien, I do understand the draw towards daily drinking. It's not for me either, never has been, but daily Ambien, I could see how I might enjoy that if not for the side effects that it kills my hopeful attitude the next day and has me making promises my actually emotional state won't let me fulfill.
