Co - parents

Feeling mad and frustrated I don’t know how to co parent with my kid dad and I feel like he does not listen he always thinks I’m complaining, starting a argument and I don’t know what to do about it we have court next month and right now I was trying to communicate something to him and he got frustrated at me and hung up our daughter sees that and thinks it’s ok I called him back because she wants to talk to him and she said why do you hang up on mom? Any advice, please how am I gonna co parent with him if he’s acting like this?
