Toxic,
I'm not sure what sort of normal you're asking about, so I can't say.
For him to detox is normal......I think every junkie tries it at least twice. Is it normal for him to go back to it? The odds are definately against heroin addicts as far as getting and staying clean.
The life you and your daughter are living right now......that is NOT normal. There is nothing healthy about it. I know you tried to help him, you were there for him, you must love him. But you have to decide how much you're willing to put yourself through, before you say "Enough." And that your daughter is involved!! That fire could have killed her....if not then, sometime in the future, when he nodds off again, you may not be there to call the fire department in time.
My advice, and take it with all the salt you want, is to get away from him somehow. Kick him out if you can. Save enough money to leave. Take your beloved girl to a safe place. You said that your family will not speak to you. My family was like that once with me (probably not exactly the same), they wouldn't talk to me about any of it, because I had chose to stick it out in an abusive relationship. I did learn that when I actually got up and left and showed up on thier doorstep with no intentions of going back to him, they took me in. I guess they were always willing to help, but only on thier conditions. Not what I call unconditional love, but I took what I could get. Do you think your family would talk to you, once you've left him?
thinking of you, keep us posted,
