Sooo, my mom and dad are coming over to the US for a 5 week holiday and staying with me. They're elderly and I dont want to upset them too much but I know they'll be asking questions. I'm at the point now where I dont feel the need to tell anybody anymore but I think I should let them know that I'm dissapointed in my W and leave it at that and they can make their own assumptions?
My grandmother use to tell us that she could deal with the truth. What she could not deal with was us keeping the truth from her, thinking we were protecting her.
How much you tell your parents is up to you. They are your parents and you know how they will probably respond. If you don't tell them enough, they may pressure you to pursue your W (thinking that will get you back together). IMHO, they should know that you are the offended spouse, and that you were very hurt and extremely disappointed by your W.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
