I found out on my partner's phone he had a secret Facebook account. Where he was messaging men pretending to be me , sending them private photos of me and awful sexually very violent and graphic messages between other men . He was also looking up gay clubs. When confronted he says he was sexually frustrated because I'm going through the menopause. I'm gutted, so hurt by it .I feel he has been cheating on me but he's says that's not true he messaged men because if he messaged women then it would be. It's awful behaviour and I feel so let down by him .
