Hello everyone. I am in a state of shock right now and don't know what to do, but I've been a lurker on mumsnet for some time, and knew this is the only place I could turn to. Last night I went through my husband's phone and found out that he has been having an affair with a close family friend for at least four years. In their messages they talked about the times they have met up to have sex, and their plans to move in together. I don't have all the information, as when I confronted my husband about it he left the house straight afterwards, and is currently staying at a hotel to 'clear his head'. I am completely numb right now. We have a 7 year old daughter and I have told her that he left for a few days for work, but I'm dreading having to tell her that her daddy wont be living with her anymore. I feel so alone right now, the close family friend he has had the affair with was my best mate, she went through a very difficult divorce last year and I helped her through it, so it feels particularly awful that she would do this to me. Any advice is welcomed.
