I have read previous threads of a similar nature on Mumsnet and I would appreciate some advice. I have been in a relationship for 20 years and married for 10 years to my partner. We married in 2007 and in 2012 my husband received several calls on his mobile phone which he ignored (it was 1.30 a.m.) and we had both been sleeping. I could hear a female voice and when he cut her off several times, the home phone rang and I answered. She said her name, Shannon, and said that she wanted to speak to my husband. She called me by my name and said "please pass the phone over to your husband, he knows who I am". As my husband pretended to be sleeping I asked her why she wanted to speak to him. She said that she felt sorry for me and that she had been having sex with my husband and then she dropped the news that she had been in our house. She perfectly described the interior and said that my husband preferred much younger and slimmer women. I put the phone down and she phoned back again. I wish that I had demanded more information but I was tired as I had to get up early for a meeting at work. She again phoned and her message remained on the answerphone. My husband explained the next evening that he had been helping someone at his workplace and that the call had been malicious and I should ignore it. I amazingly believed his story and as time progressed I put the call into distant memory cells. This was until May of this year (2018) when my husband fell out with my son from a previous marriage. My son told me in a fit of anger and despair that he had seen my husband going into our house with a female but he couldn't remember the year. He said that he believed she was a prostitute as my husband had been searching for local escorts online. I asked him if he could recall any information at all and he said that when he had seen the computer history "100% British Blonde Bombshell" had come up on a site called 'Adultwork'. I looked and under the name locally and Shannon Summers, came up. I then told my son that her name was Shannon and that many years previously she had phoned me up. My husband admitted to meeting with her on two occasions (on the second he brought her to our house). This was in 2008 as I remember her saying that we had two little birds in a cage in the hallway. They were zebra finch and we only had them for a few weeks. I had gone on holiday abroad with my youngest son as I had just completed a degree and I longed for a break before I returned to full time work. It all became horribly clear. Now looking back through credit card statements I have found many payments to Adultwork made in 2012. My husband also continued searching for local escorts as my son took a screenshot of his computer. Whilst 10 years ago I would have thrown him out immediately I am wondering why I am not doing so. I feel sure I will come to a decision as it is tearing me up inside. He is trying to convince me that he only met with her twice but why the gap of three years plus before she phoned? I feel like the past 10 years have been a sham and that I am an idiot for not challenging him earlier. Surely a prostitute would not remember him after that period of time. The stupid part is that if I was reading this comment from someone else my advice would be to run and keep running.
