Something happened yesterday that has me at a loss. I recently met the wife of one of DW coworkers. We talked at a volunteer function we all were attending. A few days later, I emailed her to thank her for her time since this was her first time working. She emailed me back. My wife was looking over my shoulder and saw it. Then, she proceeded to have a "moment." In eighteen years of marriage, I have never witnessed this. I told her ahead of time I was going to email her. My email account is on the desktop and not password protected. I told her I may email her again since we have common interests and she seems like a nice person and she said it would be fine. DW travels with her husband and I have no problem with this. She knows I have a strong opinion on infidelity. I have lost good friends over it since I believe it is unforgivable. I have never given her one reason not to trust me. Why did she react as she did? She seems okay now, but I am not sure. She has traveled a lot since we were married so trust has to be complete.
