Question about "Amazing Adventures of Kavalier and Klay"

The book by Michael Chabon. I read it months and months ago and something always nagged me about it. One day when the kid was visiting his Uncle he saw his mom on the train and she was dressed up “with lipstick” and was embarrassed to run into her son. We know that her husband was gay and that the marriage wasn’t great but there was no direct mention of adultery. As a matter of fact, that is the only indication of it. Do you think that is what Chabon intended to insinuate? If so, don’t you think it was left a little too open and vague?

I think your supposition is correct, but why not go straight to the source?
