No kidding, EVERYTHING has to be on their terms, their time. That is why I get annoyed when people talk about PUSHING their spouse back into their tunnel. There is NO WAY of knowing what will or won't push them into their tunnel. They CHOOSE to run back in, whenever there is any sort of confrontation or heck, even communication that THEY DID NOT INITIATE...!!! How in the world can we predict what will trigger a response, positive, negative, indifferent?
TRUTH is people... just please yourselves. You are aware of what you are doing, what message you want to send, if he/she does not read/hear/see it the way you intended, that's too bad. Hopefully, some day in the future that/this moment will be remembered and maybe then they will "get" what it was, you were trying to say.
Until then, just be true to yourself. Say whatever you want, when you want... JUST SAY IT NICELY! No hostility, no spite, no nastiness... simply STATE YOUR POINT. Charge neutral and leave it at that. If they try to argue with you about it, simply say, NOTHING to discuss, I am simply stating what I was thinking. End of story. Leave it at that.
