We know she worked a lot, wasn't very present, and I get the impression Jake (and Gina) was mostly raised by his grandmother.

Jake said he and Gina didn't have dads 'because divorce', so I'm thinking yes.

STOP. I had JUST gotten over it.

In fairness, Jake is/was 33. So, not much difference, but at least then you can say his dad was early 20s.
