Cry me a river, Urbs.
Of course he was depressed and stressed. Trying to balance an affair(s) and not drive your family away , at least in in the public awareness to preserve your image, can get stressful. Admittedly this is rumor, but without knowing anything factual, I noted, the 2nd time he resigned ( red flags popped up all over the place in my mind) at one point there was a change- He no longer sounded like a coach leaving, but a guy making a desperate public attempt to sway his family ( wife) and convince them (her) not to leave him. The desperate tone in the voice, the wording, etc. Mr Manipulator probably had gotten sloppy with infatuation and overstretched his ability to con,and no doubt had broken some previous "heartfelt" promises..
After he left, my sister told me her daughter, then in college, had told her it had been common knowledge in the frat/sorority circles at USF for a year at least , who he was seeing from one of the sororities. Who knows if true, but it was certainly an enduring rumor there.
