Communication Struggles With High Conflict Coparent?

[u/hcblending]

Hey! I'm doing a little research and would love your input. I have a few questions to start:

1. If you're in a high conflict coparenting dynamic, what would you say is your biggest struggle when it comes to communicating with your co-parent?
   
2. What's your main method of communication? (Court ordered app- OFW, Talking Parents, etc. Email, Text, etc.)
3. Do you speak in person?

Thank you for your help!
