My partner was asked to attend a work meeting where he was accused of writing malicious letters about 2 of his colleagues( 1 his former boss)where they were suspended pending enquires and his former boss left because she couldnt cope with the stress of it all. He denies it, but I know he is guilty as I have seen these letters on our computer, although I wasn't clear then what he was doing(he has deleted them now) I have confronted him with it but he continues to deny it. I am really concerned that he could do this to someone else and he's not daft -he knows procedures for complaints! Ive told him unless he stops lying and tells me the truth our marriage is in serious trouble as I cant trust him. I have 3 girls and dont want to go down this route but I am deeply shocked by his behaviour and continual denial. Am I over-reacting to this?
