Welcome to the beginning of your journey. Coming here to SR is a great place for support and information.
Start one step at a time, read around, and know that you don't have to solve it all in one day. Just one step at a time, and the steps will often come clear to you on their own.
Today, you took a great step by posting here and "meeting" some folks who are familiar with your type of world. Pat yourself on the back for making a step of progress, today!
One good place to start is reading the "sticky" posts at the top of the topic page - they are classic information about this road we've all been down.
Another good resource is Alanon - a support network all over the world for friends and families of alcoholics. Google Alanon to find a local group of folks who've gone down your road.
We know your pain and quandaries, so come back and post often for support. Take it one step at a time, and know you are not alone in this journey!
Sending encouragement, and others will be along shortly to respond, too,
