We have been together for 27 years and have three dc. I have fairly solid evidence of ow. He has been messaging her a lot. He says they are just friends I have recently managed to read his Facebook messages and although they stop af around two months ago I know he has still been I contact with her. He told me tonight that we have never been happy and because I have threatened to leave him in the past. I do wonder if this is because I have found out. He has met up with ow for walks, (he says just the once but I'm not convinced}. It's clear the trust between us has completely gone. I don't know what to do, I'm utterly beside myself.
