it's that she wasn't honest about disclosing her sexual past to her man about this dude who is her friend.

I feel if there was a scenario where they got married, and dude started a new job, and a new coworker had a romantic past to his wife, he'd prolly feel some kind of way about that too.

but ultimately it doesn't matter. It can't matter. Nothing is happening in this story but bruised hurt dude ego. Lol like marry your wife and get over it.
