Hi Roberto,
Welcome to the Forum.
I may be going to sound harsh but I really would think about what you are going to do, living with a cocaine addict is hell, and I mean hell, your life will not be nice, he will spend all the money and you will never know where he is, and the lies are terrible, they even believe their own lies.
Sorry to be harsh but I am only speaking from experience.
Take care.
