I think being in the state of denial is the only way you can live with an addict. It's almost like you detach from yourself and reality and live in an alternate state. If you (not just you, anybody) were truly in touch with reality, and the absolute madness addiction creates, you would do one of two things, leave the relationship or go insane. I think the ONLY way one can stay with an addict, is to deny reality and all those who are damaged by it.
