Baby mama drama pt.2

The father of my child and I have been split up for over a year. We are both married and he has another child. Anyways!!! He called me yesterday. Checking on our daughter. We discussed her birthday and decided to go half on a big present for her. Well, he calls me today and it's his wife telling me to never call or text his phone ever again unless he's getting our daughter. I informed her that he called me and we only discussed our child. She hung up on me. I sent her a screenshot of my call log to let her know I don't call him. And she got so pissed. Proceeded to tell me I'm a piece of shit mother. Said that she is my daughters step mother. And that I need to respect her. Not gonna lie, I got a little pissy and basically told her she wasn't shit. And that I've done everything they've asked. I had her number blocked and she went out of her way to contact to me. She told me my baby daddy told her she could call me and basically start shit.

Her number is blocked but I don't exactly know how to go about asking him to tell her to leave me alone. She's a disrespectful manipulative little shit. Honestly. I'm all for co parenting but she does not like it when he's civil with me and she's making it VERY HARD. Any ideas on what I should do?
