Why does my ex still cuss me out after 5 years break up?

Menyou2
My ex and I dated for 12yrs I asked him if we were gonna take it to the next level he said no and I’ll admit I did the immature thing and went out and started seeing other people he found out and we split he stop talking to our daughter and said he would tell her later in life I was a whore fastfoward 5 years he still no matter when he sees me cuss me calls me bitches and says he hates me I was toxic... but he never worked when we lived together and so many other things like being abusive... I’m willing to let that be to co parent but he won’t blaming me and he refuse to look me in my face when we see each other.
