Hi Aquiana,
The decision to stay or leave is up to you. There are success stories here for people who stay and people who leave. It is true that we can't "fix" them. But by reaching out, you are beginning to fix yourself. There is a lot of hope and healing here. Many of the members here are members of Al-Anon. It has been a great source of support and change for me. I have stayed with my husband through the good and bad, and I don't regret it. Al-Anon has helped me to see my life as my own, not as a victim.
Stick around. Read the posts. You will find that you are not alone in trying to deal with the effects of alcoholism on the family. We have all been there, and it does get better with love and support of people who understand.
To find an Al-Anon meeting in your area,
