Juke, do what you have to do to protect your heart. I think you should try to be there if you can. I was there when the sparrow took the last of her essentials from the house. It was incredibly painful, but I sucked it up and stayed cool and pleasant in her presence. I didn't put my hands over my face and bury my head in the couch until she was gone. While she was there I hugged myself and doubled over a few times while she was out of sight. My guts were a pretzel.
I think you've had a hard time following the advice to take WW's words with a grain of salt. I know that my WW's friends and family have pulled away from me because of what she's said to them. I can imagine, and it hurts me terribly knowing some of what has probably been said.
And just last night my mother said, "But she said even if things don't work out with OM she probably won't come back to you." Many people supporting me are worried that I'm in some unhealthy state of obsessive denial. I have to constantly remind them that I know where things stand and that I'm just doing my best to fight for my M, not fooling myself about the likelihood of my M ending.
If it's too hard for you to do that, then you might have a tough time being in plan A. It is grueling. It's like being fed mouthfuls of sh*t, swallowing, and opening up wide for more every time.
H4F told me this a while back:
"Don't listen to the masses that say 'I think she's really going to do it, you need to let her go etc...'. They are the same people who will be shocked when you're back together and praise you for holding on as long as you did. People often take things at face value - there is so much more to all of this than they understand."
You have to believe this to be able to endure plan A, my man.
