Hi,
I agree with what has already been said. I suggest that you find an Alanon or Naranon meeting and the sooner the better. You can get some phone numbers from members there and gain support from people who understand addiction and codependency.
Many well intentioned people will give advice, but in the programs mentioned there are tried and true ways for a person to learn how to live successfully with an addict in or out of their life.
You can't control him. The only control you do have is what YOU decide to do for yourself.
Once you have learned a bit, you will be more able to decide the best course of action for yourself.
I'm so glad you found us here at SR. Please keep coming back because there are many here on this forum who have alot of experience with exactly what you are facing.
