i have had enough

I am so sick to death of my husbands selective hearing and ignoring.
Our almost 2 year old decided she wanted to stop wearing nappies and toilet train a week ago. She is doing amazing and has only had 6 accidents. That is okay. But they have all occurred when my husband is watching her in the evening while i am cooking dinner or cleaning. She tells him wee or poo and he just doesn't listen! If i say, "she needs to go potty", he will take her. But he just never listens to her. It's not just that either. I will be in another room and hear her ask him for water 5 times and he is standing there holding her, watching tv. Eventually she gets upset and starts crying and he goes mad at her saying, "what do you want? Stop sooking and tell me what you want!". Now she is really clear. But by the time he has ignored her multiple times, she starts to become incoherent because she is really upset. It happens with something every day and i just want to punch him in the fucking head! Tonight i was in the toilet and i heard her say she needed to poo. He just says "yeah babe" and i hear him walking away. Then she starts saying "poo daddy, potty" over and over and i hear him from the lounge saying "come here honey, watch tv with daddy". I come out and she is crying in the kitchen, pooped her pants and he is sitting on the couch watching tv completely oblivious! She is so clear, there is no way you cannot understand her, he JUST DOESN'T LISTEN! He also does it to me all the time and i am sooooo sick of it!
I don't know what to do anymore but i have just had enough.
He swears literally constantly and she is now doing it too. Today she laughed at him and called him a funny c***! It is like speaking to a brick wall trying to get through to him. He comes from a really lovely family, they are well off and just wonderful. I don't know how he can be such a disgustingly feral slob.
