Yes and no.
I suspect that like many women, she was in denial, but did not "know" 100%. My brother attended and graduated from from FAMU. I hung out on the hill quite often, plus we were friends with his wife, which in turn made us acquaintances of Mr. Gillum. Although he wasnt very masculine, he wasnt sweet like the known gay boys on campus. Also, if he was gay then, noone he was "with" ever outed him. Even when he stayed and began his political career, no gay/ sex scandals bubbled, they had a public marriage, hes APhiA, and they have kids.
People like to use the term "metro-sexual." I dont. In most cases when a woman dates a dude who turns out to be gay, I feel no sympathy for the woman, they know 100%. In this case, I can see her unwillingly missing signs at home due to all of the other co-factors. Hindsight is 2020.
She knew. I know them and my ex-wife pledged her, as she is a Delta and went to FAMU. She is a beard. Dude was running around with gay dudes in college. Many rumors. She ain't blind she ain't deaf. She is a very intelligent woman.
