Welcome to SR.....you'll find that everyone here understands what it is like to love an addict.
You've taken a very positive step in taking care of yourself and that's a HUGE first step. Self care is extremely important in the process of recovery.
I hope you stick around and read the stickies. There are some fabulous books that are recommended reading when dealing with an addict (CoDependent No More by Melody Beatty is one of the most recommended but there are many!) I've also found great comfort in Alanon or Naranon meetings.
You are not alone.
gentle hugs
