Welcome LoveHim
Glad you are reaching out for support - I also encourage you to read the stickies and other post. Also if you have not attending any Al-Anon/Naranon meetings - those would be great also. You may be shocked to find out the people who share your same story.
Also you can try reading recovery literature - How Al-Anon works for Family & Friends of Alcoholics, Courage to Change in Al-Anon and many other books about how we are affected by another person's drinking/using.
Stepping back from the situation and focusing on you can help you look at everything with a different perspective. This way you can make an informed decision about what is best for YOU.
Don't give up before the miracles happen in you - You deserve them.
