This is the third time I've caught my husband messaging or msning other women. The first was on msn I walked in on him on the computer and he turned it off but I saw that he was on msn with a woman. The second time I was on msn and this same woman logged in and talked to me thinking I was him I pretended I was and stayed on line with her the third time was I found a text message that he'd sent to a woman at ten in the evening saying "hi what's up i'm off to bed!!" anyway when I confronted him he went very red in the face and insisted that she worked with him and they'd been friends for ten years - when I pointed out that if she was a friend how come he'd absolutely never mentioned her he admitted that she worked at one of his companies other offices (which by the way hasn't been opened for ten years) - anyway every time I push him into a corner with statements that prove he's lying he backs down. His apologies and excuses have always been the same "i didn't think before I sent her the messages and I'm sorry I promise never to do it again, please forgive me let's forget it ever happened, not for me but for our daughter' and now I just don't know what to do.
