hi bigisland,
i'm sorry you are going through this. i know it really hurts. i don't know that much about your story, but have you considered al-anon or nar-anon? you will get a lot of support there and help healing yourself. just because you broke up doesn't mean it magically gets better. . . i know you know that. you really do need to heal yourself--being with an addict is is toxic and harmful.
hugs to you sweetie.
