If you need to communicate face to face or on the phone limit what you say. If they say anything abusive just cut them off and walk away. I agree with the above poster though. To only communicate via email and text.
Yes. Communicate via a co-parenting app. Cut the Facetime as it’s just another avenue and he may view it as disrupting his parenting time, be a trigger for your daughter missing you. Have extremely detailed parenting consent orders in order to limit any need for negotiation, communication or misunderstanding. DISENGAGE, DISENGAGE, DISENGAGE. Do not respond to anything that doesn’t require a response and if you need to, keep your response minimal, factual and non emotional.
My friend recommended this book (Parenting Toddlers: How You Can Use Positive Discipline to Raise Kids Who Will Have High Self-Esteem, Including Tips for Sleep Training, Handing Tantrums and a Guide to Potty Training) and it’s honestly been a huge game changer for me, it’s been so helpful in so many different aspects of parenting!
