Thanks for the Vent and Welcome.
Does DS8's dad have any legal decision making power over you? IF not 'yippee!'
It does stink that you don't get more support from him, but like so many family members, some get it and some don't.
LoL on the 'only Very Superior!'
If you can apply to Davidson YSP, do it, it might (or might not) make an impression.
Most people who grew us gifted, just do not understand that there are levels of Giftedness, that require very different action-plans. I sure didn't.
Maybe give him Ruf's 5 levels of giftedness as a present, 'since his DS2.5 is showing so many signs of giftedness.'
Most intact couples come to 'get' their children at different rates. Most Gifted Adults have plenty of baggage of their own 'one way or another.'
