I just got back from the best time i've had with my kids since there mom and I split up. I just dont know what I can do about them thinking its okay to talk to me the way there mom does. I try to explain its not okay, I explain it is hurtful, but there mom laughs an jokes with them about it giving them mixed messages. Is there any way I can get on top of this or is this something they are just going to have to grow out of?

I am not sure if im looking for advice or tips or tricks or what but well im being lost

Any ideas how to help keep the peace in the future because spending 4 days with my kids mom and her being so vindictive that the kids start asking me what's the matter, weather she will talk or not anything I can do to to at least know in my own mind ive dont all I can. I am kind of in that mind set now as it is but a shot in the dark its totally possible I over looked something.
