I agree with HardLessons. Let him go. He will do whatever he will do and nothing you say or do will change that. You have a daughter to take care of. The last thing she needs is an active addict in her life.
You do deserve better. He was right about that, but he has moved on and told you to stop contacting him. Let him go. Take care of yourself and your daughter. I highly suggest you find an Alanon meeting and start attending.
