What to do when you are in love with an alcoholic? You cry and get angry. You feel stressed and frustrated. You realize that you don't really have a partner anymore. You feel alone. You do what you are doing....try to figure out what in the heck to do next.
Start learning everything you can about alcoholism. You read books and do online research. You talk to folks here and maybe you go to Al-anon.
You have to decide if you want to live in your current situation or not.
Whether or not you stay in the relationship, you have to figure out how you are going to live and fine peace of mind while you are living with an alcoholic.
Alcoholism doesn't get better. It's progressive. None of it is your fault. You can't fix it. You can't control it. So learn what you are dealing with and learn to take care of yourself.
