When somebody walks out on both a W and small children they are aware on *some* level that they are forever damaging the R with their children. The WAS may never acknowledge the damage they are doing but they are aware. Any form of "fixing" by the LBS smacks of control and will only push the WAS away. Your W has not at all been receptive to your parenting tips so this you should know.
If the WAS chooses not to co-parent in an appropriate and proper manner then the LBS must act "as if", be the best single parent they can be, move forward w/o the parenting assistance of the WAS and let the chips fall where they may when it comes to the R the WAS has with the children. A LBS can't "fix" that R and it must be done by the WAS. Sometimes it's too late and other times it's not. At the end of the day the WAS is a grown man and if he desires an improved R with his children he will move mountains to reach that goal and will work hard to use all resources available.
But no, unless they ask, the WAS isn't interested in resources, books or websites to improve any R's - it pushes them away and reminds them of the destruction they caused.
