It will get better as time passes, I promise. Lord knows I have done it way too many times myself. Have you investigated why you got involved with an alcoholic in the first place? You may have some underlying issues you may want to address so that you can choose and/or relate to others better in the future. At least that is what I try to focus on each time I leave another relationship. You may not have moved on yet simply because you are not READY to move on. When the time comes, you will know and your heart will be freed.
