Thank you Hal_al.
This was my general interpretation with the caveat about the interpretation of the support test that I described above. Mainly, I questioned my interpretation because my ex-husband seems very convinced about his position. That made me wonder if I was missing something. I'm feeling a bit better about my interpretation of the rules now. I'm also clear that per the tiebreaker process also spelled out in the dependents and divorced parents caveat section, that the final decision on who gets to claim is who the child lived with the longest. And that is most definitely me.
Thanks again
Krisa
