After she admitted that she did text him she managed quite successfully (with tears offcourse!) to convince me that I should not rubbing it off on her face anymore which I agreed though I told her she needed to learn from what had happened. Since that night, she tried to convince me that everything was back to normal. She started to show me the text that the guy had sent her (nothing that raised the red flag, really).
Then, about a month after her confession she told me that she was affraid of getting pregnant because of our passionate and rejuvenated sex life. I told her jokingly that I really did not mind to have more kids as her sister also recently had another baby, besides the chance is very slim for her to get pregnant again since she had her tube tied 8 years ago when she delivered our youngest daughter. But she seemed so concern about it and asked me to buy her a pregnancy test. I did buy it and it turned out to be negative (off course!!).
I actually do not want to play shrink here, but her distress mood about the possibility of getting pregnant were never happened, and it bothered me. Later when I was able to check her past schedule, I found that there were days my wife and that guy (only two of them) had to come early before the rest of the shift. So yes, the opportunity was there for the physical contact and I was blind all this time.
When I asked her to avoid making contact with him except their working contact she seemed to agree. Then it turned out that this guy always had reason to contact her. Once, I asked my wife to skip working on his shift, he quickly text my wife to show his concern and offered her to take another day off. There was also an incident when I dropped my wife at work early in the morning all of sudden he came (lucky me I was still there when he arrived)then I could see my wife panicking, convinced me that he should not have been there that morning. I did not say anything and tried not to be prejudice. Then my wife went in to the office with this guy (again only two of them)and moment laters I saw him shot off and my wife came to me saying that he must have been wrongly read their rota. I ended up helping her that morning before another person came and helped her. Now it was not that difficult to find out that the guy had actually worked till night the day before that (usually they finish around 12). And it would have been impossible for him to have another shift this morning, he knew that, my wife also knew,and I was the dumb one.
I know I am still in denial of all this although the signs were there all along........
