I second Cali's post. You have turned a tough situation into a life for yourself you can be proud of and at the same time teaching/showing actions that will benefit your daughters in their interactions with many people as well as their mother down the road.
My kids(now adults for most part) have learned much in dealing with difficult people as well as their mother.
It takes a rock and a roll model who is healthy themselves to show them the wisdom and knowledge they can use themselves.
