“Don’t tell me what to do” - father of my child

Basically my child is going through that lovely terrible twos stage. She refuses bed, struggles when you change her, says not a lot. Thinking she’s playing she also slaps which is all stuff everyone deals with during this stage. I’m fine with it, I crack in and if she needs telling off she gets put down, firmly told no and I walk alway. However her dad is a different story. He’s in her face, shouts at her through gritted teeth and will just drop her in the sofa rather than place her down. It’s a disgrace and I’m sick of it and I’ve told him so many times to cut his shit. He tells me he will do what he wants and not to tell him what to do however BELIEVE ME I will ALWAYS tell him when I feel he is in the wrong. She’s a two year old, she’s not fully understanding of everything and him treating her like that is NOT ON. I’m honestly SO angry. I feel like if I wasn’t worried about having to split custody and there be days that I wasn’t around then this would end our relationship. Feeling super stressed out about it all and now once again we aren’t talking! Fun!
