Anyhow, the sad thing is, during a divorce we can't protect or children from what an x-spouse may do (within legal limits). The best we can do is try to stay rational around the kids. Don't let them see you getting emotional or angry at your husband about this. You can calmly and logically explain why the behavior is wrong and that when they grow up you hope they make better choices.
Exactly! If the kids come to you with questions on what is right or wrong, or what specifically is bothering them, then address them openly but with age appropriate responses.
Be the strong one for them and they will appreciate it!
