I wanted to let you know that I too made many plans w/out H and the girls and I just went by ourselves. There was always this underlying sadness or disappointment that he didn't come. And yes he always had an excuse. Too tired, busy gaming, wanted to vegetate, etc.
I too just noticed that the girls and I can do so much more without our parade being rained on.... he really was like a dark rain cloud all the time anyway!
And yes, your H is spinning out of control, and getting more angry about it by the minute. Let him retain all the attorney's he wants, and quite frankly that's just a threat anyway.
Yes hold it together. You've got a grip my dear! He doesn't!
