Michelle, you are losing your mind more every day. You have no clue what you are talking about. have you not figured out that sometimes people do the right thing the first time, as the OP did and just letting things play out is the right thing to do? You have an absurd sense of what a relationship is all about. So, this guy, in your insecure mind, after telling his woman there is zero interest in this other woman now should stay clear of the other woman just to prove his loyalty? hahah, that's BS. How about his woman changes her behavior and gives the guy the trust that he deserves? Yeah, I Know, crazy shit, eh?
As far as my wife goes? even funnier. So now my wife is not worthy of my trust and unable to resist advances (if there are any) from male co-workers when traveling? Ohm my gawd, maybe I should demand that she quit her job or tell her boss that she is no longer allowed to travel unless the company providers her a chastity belt. There are no reasons to suspect my wife is having an affair. I do not expect her to lock herself in her room or wear a burka just because I am not around. The problem with you and many of the other commenters here is that you do not understand the difference between "blind" trust and "complete" trust. I have complete trust in my wife because I know the type of person she is and her moral values. Blind trust is when you think you can trust somebody without knowing enough about them to know if they are trustworthy. Then.... there is the "conditional" trust that you and most of those here afford their partners. Conditional trust says I will trust you as long as I can keep my thumb on you and you follow my rules and eliminate anybody from your life that "I" perceive as a potential threat. Newsflash, if you have to make conditions or ask your partner to limit contact with others then your relationship is lacking in any meaningful trust and is a complete sham.
Could my wife end up screwing around with a co-worker? From what I know about her I would have to say no. However, anything can happen but sitting around worrying about stuff that may never happen is plain stupid.
The bottom line is simple. You give advice based upon your own view of how relationships should be. The problem is you have a great deal to learn and your inexperience screams loud and clear. If everybody followed your advice we would all either be single or in counseling, or both.
Tell me Michelle, How does the real life work? I would love to hear your answer because it seems your "real life" experience is based upon a 5 year relationship based upon conditional trust and an amateur advice web site.
