If there is anyone I feel sorry for it's your daughter
I don't know if this idea has occured to you BUT from what I've read, and from your previous posts too, I would bet money on the fact that your daughter is probably naming off your bad traits/habits/acts to your ex as well, because she is trying to get someone to pay attention to her while you and your ex are fighting it out and/or making it up.
If you can't start building a support network of your own and making some permanent decisions based on facts, not possiblities (i.e he may actually stay home tonight and watch the kid) for your own sake, do it for your kids. They haven't asked to be in this situation and as an adult and their mother it is your job to act responsibly, saying you don't have to because he's not, or trying to put all the blame on him just doesn't cut it.
In Al Anon they say there is a difference between being a victim and being a volunteer. Victims generally are involved in a situation which is a one off random occurance.....
