One of my chief concerns is that she has surrounded herself with her mother and new and old friends that will reinforce her decision and encourage her to move on, live her life, explore the greener grass - even if she is not really technically in that frame of mind. Yes, I suddenly do not have a lot of well-wishers in this. My biggest fear - based on how planned and calculated her 'exit strategy' was - is that she actually DOES want to move on. I cannot see why else she would block me on Instagram if not to hide what a dandy old time she is having? I know I can't control this but, I find it extremely painful to bear. It is as if she took a pair of scissors and cut me out of her life. Nevertheless, these words of yours keep ringing in my ears so I will do my best to '...be her lighthouse. Be where she left you (but a stronger, calmer and happier you). Be bright and strong and reliable. Be kind and loving (from afar). Let her decide how close to shore she can risk coming.' Though I can't sometimes help feel like a right mug about it.
Mine did the same thing - they all do that...surround themselves with people who validate their decision. Do you think they'd rather be with people who say its a bad idea? No, they don't. They hear what they want to.
Now, don't worry about the reasons for her blocking you. I assure you it isn't to keep you from seeing how "good" of a time she is having. More likely that she wants nothing to do with you seeing it...and maybe even the relationship. In the grand scheme of things, does it matter why?
Remember the butterfly analogy that I use so often? See, think of your wife/marriage as a butterfly. What happens when you squeeze it in your hand? Kills it, right? So, what's best for the butterfly? Yep - it needs fly...fly away and do what it needs to do. Its up to you to provide a safe space to land on. If - and that's a big IF - she chooses to alight again on your opened hand, then that's great. But, if she chooses not to, then you best be ready to fully grasp and live with that.
There are moments in this life when you are so confident in the rightness of your actions, that not even for a second do you consider the option that you might be wrong.
