Found text message saying "morning xxx" on Sunday morning from colleague at husbands work who I felt instinctively I had cause to worry about. He had "lost " his phone previous week and let me take mum home in car at night without one now for obvious reasons.He denies any affair but admitted he had let her get close to him by listening to her relationship problems.I don't believe him because I think the text message is far too personal . He has been on business trips with her.I need to know what others think about message on his phone please.
