Welcome to the SR family!
You will find support and information here for yourself.
I have found a lot of wisdom in the permanent posts at the top of this forum (sticky posts). When I read those posts, I find that I am not alone and I find inspiration to begin taking better care of myself.
The tools that have helped me in my day to day life are:
SR, Alanon meetings and self-help books like "Codependent No More" by Melody Beattie.
Please be gentle with yourself. You are ending a relationship with someone that cared more about alcohol than anything else in their world. Give yourself time to grieve the loss of what could have been. Give yourself time to re-discover the desires of your heart.
We're here to support you. (((hugs)))
