Father Needing Advice on co-parent Co-Parenting

[JamesShire]

Hello all, first message here.
I am really needing some advice on improving the relationship with my ex, we have been agreeing access with the children for the last 3 years but over the last few months we are only communication by email and it is just arguing (im as much a problem as my ex partner). Does anyone have any advice on how to fix/improve this as the current situation is not working and rather tiring for both of us.

What are you arguing over?
So in terms of contact set days where the kids are in either house then outside of that there is no need for discussion.

Try to do hand overs at school as it minimises the amount you need to see each other.

What other issues are you facing? Hard to advise without more detail

What are you arguing about? Don't you have a set routine in place?
