I am new to the site.. but not new to the scenarios of OW, and MLC.
My thought is that we all have our own "reality". It is possible these beloved mates of ours can thrive, with a completely different world view? Perhaps right up to their last breath?
I could not do this. Perhaps you could not do this. And yet, there are beings who have themselves in such an altered reality, that 10, 20 or 30 years with someone other than the ex spouse, and the children, is fine for them.
I would judge these men and women as "lost souls". And yet, I come across these beings fairly often. Some are on marriage number 3... or 4. They seem incapable of knowing what it is I believe to be true. ... And , of course, what is true for them, I can not see.
Which brings us back to us.. the self. What is it that we thrive most in? Commiteed, loving, respectful relationships, fidelity, adventure... without a lot of storyline, or drama? (that would be my list.. not yours)? The challenge then is for each of us to live our own boundries.
