If this got out, it wouldn’t just impact Brook and his XW and friend but the coaching community, the players, etc... I am sure he is feeling very overwhelmed.
Yes, Brook is probably feeling overwhelmed. He’ll find his way.
I believe it is a matter of “When this gets out...” not “If this gets out...”. Most stuff surfaces eventually, not too many people take secrets to the grave. Brook’s XW can spill the beans at any time depending on how scorned she becomes at his friend. Or any other number of sources could speak up.
The larger impact is usually and amazingly short lived. It’s incredible just how quickly scandalous behaviour is collectively glossed over by the bulk of a community, and even with one’s friends and acquaintances. The impact upon those immediate to the situation is of course a different story.
Taking the high road is good advice. I believe the high road for an EA might be different than for a PA / affair. Food for thought.

Feelings are fleeting. Be better, not bitter. Love the person, forgive the sin.
