So my partner and I split last year and within weeks he was with this new woman, obviously part of me believes it was going on before and they used to go out together frequently whilst I was at home looking after our children (not on their own but as a group of colleagues) I feel so stupid as I did question it at the time and she was just a friend apparently. I had a few wines the other night and stupidly messaged her just asking when this started, obviously didn’t get a reply
