You need to do what is right for you. I don't know all the details.....and I pray that all goes well. I certainly wish no ill toward the OW or anything like that.....and I hope I didn't come across as sounding that way. I just didn't want you not seeing what might be happening, b/c people's mental & emotional state can be very fragile when something like this happens. As you know.....all "kinds" of feelings start to surface for each one in these two families. I think you know that you are in a difficult place and you have to be the one to decide how to deal. Just wanted to make sure you "saw" what seem to be obvious to me. I would not look forward to telling you that "I told you so" and I pray that you will be able to tell me that "all is well".
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!
