Okay, this is the point at which I call bullshit on this story that you are regaling here. It’s either a great piece of fiction that you are pulling readers in by pretending that it’s an unfolding story, or you really have gone over the edge of reason. Why on earth would you put yourself in full view of anyone who might know or report your identity, and yet still not take any steps to initiate divorce proceedings? Why would you be playing with fire like this?
If you could hire a PI without his knowledge then why aren’t you hiring a top lawyer to represent you and advise you on the exact steps that you should be taking in this scenario?
My only other thoughts, if there’s really any truth to what you are sharing, is that you have all out plans to create such a fantastically juicy story, by getting all the details that you can before taking any legal action, so that you have something to sell and profit from, knowing that he may well do whatever he can to hide his wealth and leave you with a lot less than you would otherwise be entitled to.
You certainly are a mystery but I don’t believe that, if you are really telling a true story here, and sharing all the details as they are, you will not find yourself facing a major confrontation soon that could both endanger you and put you in a very emotionally vulnerable position.
