Honey, I just think Duff is 100% right. Look up Alanon meetings and go to one...your life will change. You will have support and understanding and better tools to help you and to guide your decision-making here. If you have time, it will be well worth it.
EDIT: One of the things I love about Alanon/Alateen etc is that they exist purely to support and help people affected by well, those of us who drink/drank. There is no shame walking through those doors....it is different than going to AA and feeling the things we felt when we walked in....it will be wonderful.
