Thanks to everyone for the perspective (especially from the men out there), it helps to hear it from someone else. It's just so frustrating because things don't have to be this way. He's just on a mission to "make his own decisions" and has become convinced that we are just wrong for each other. It would be easier in some ways if there were another woman involved, or some reason I could get my brain around. But, if just seems that - while we do have issues to tackle - he's rewriting history in his own way, not seeing the things that he did or didn't do that could have helped us.
This just isn't the person I knew. And one of the "telling" things to me is that he hasn't told hardly anyone about our situation, hardly any friends or family. He says this is because he doesn't want outside input into his thought process, which to me waves a big red flag. I believe on some level he knows that much of what he's doing is not logical, and he doesn't want to hear about it. I wish - when they do find out - one of his older male relatives will shake him by the shoulders and say "grow up! be a man, and figure this out with your family." But sadly, it likely wouldn't do any good. I remain convinced that when he's out on his own, he'll begin to regret his decision. I just don't know if I'll be in a place to forgive and forget then ...
Anyway, I truly appreciate your taking the time to write back. I will continue to do what I need to do to preserve my sanity and livelihood.
Good luck to you all, and we have to believe that there is something better out there for all of us! Take care.
