Things did actually change more than that though, gam. At the time you mention, Dad had all weekends. I asked for EO. Judge split the difference at three out of four. (If you look again, that is what I wrote further up the thread).
The recent 50/50 on the summer was a concession I made when his attempt at becoming custodial parent failed. And when I ran the numbers, 50/50 vs what he was getting amounted to an extra 4 days. I gladly said: have at it. *Which was all surprising anyhow, given that Dad did not want any summer time for years.
Dad would not get 50/50. At the time he was screaming he wants more time - he moved farther away. He lives 45 miles away. I think he just likes to fight; I am not biting.
The reason the understanding is not there now is we have always done it where I got a weekend - first one on typical months, second on months when Dad had first due to him having a holiday. And we have always done it if my holiday was the first weekend of month, I'd get another additional weekend (believing that holiday time was extra time). So now Dad is suddenly saying that is not how it's supposed to work and I'm doing the reasonable thing by keeping an open mind and asking questions here rather than digging my heels in. And in asking the questions, I've come to see that we may indeed have had it wrong all those years and I'm willing to acknowledge that. But that, to answer your question, is where the confusion came from.
Just to be clear, I never mentioned a thing in the thread about contempt charges, or going back to court for an EOW schedule. I'm just here asking and learning with an open, discerning mind.
