i’m sorry OP, super happy your husband was honest with you and trusts you with the information, i know it can definitely make you worry and uncomfortable but i think since he told you immediately it shouldn’t be too concerning longterm, just continue to have open communication and journal if needed
she’s not being insecure, she trusts her husband obviously but she has no reason to trust a random woman he works with, the woman probably knew previously that he was married and didn’t care to respect that boundary so why wouldn’t OP worry? heaven forbid she cares about her husband
