LNL -
You don't have to justify your anger at H to me. Just trying to point out the places where his requests ARE legitimate, so that you can stick to the high road and get him to be more cooperative.

My point about the last part was that you have never really told him you don't want to be friends anymore and are done with him. It may ease the confusion and pressure over you not talking to him if you make that a little clearer. Maybe just take a simpler way of stating it:

"H - I've paid the taxes in the amount of XXXX. Of course I will make sure D calls you - what times would be most convenient for you?

I informed you of our travel plans as soon as I was able to make them - I had to wait to make them until you confirmed which month you would have D.

At this point I really prefer to keep all of our communications via email if possible. It seems to me that this is a much clearer way for us to communicate, and should eliminate any confusion about D's schedule etc. I hope for D's sake that we can just stick to co-parenting issues and keep any conflict to a minimum.

Be well"
