When JD Vance says, "My wife has three children" – he does not refer to his wife by her name (Usha). He also does not refer to any of his 3 children by name (Ewan, Vivek, and Mirabel). And most importantly (red lights flashing, sirens blaring) – he doesn't acknowledge himself as his daughter's/sons' father (i.e., "Usha and I have three children"). All three of these are significant distancing behaviors.
