Cheating

Found him telling old coworker I'd met with him before in passing that I'd cheated on him (i have not) and asked her for a massage making it seem as if he goes unnoticed at home! For all I knew my marriage was peachy, he says he was out of line and nothing physical ever happened it was only the messages. Gave me his fb too. I feel he's being honest just curious how others view this scenario.
