I`m just right at that same point too. In fact if you substitute the W for H in your above post, I could have written exactly that post.
Difference for you is that at least you`re going to Retrouvaille.
After our very rare big convos (four in maybe the past six weeks and all H initiated) H shuts down again. Back to mumbled hellos, monosyllabic answers etc. I`m trying to break that by asking him open ended questions-What,where,when type questions.
And of course, ignoring the silence. Just having fun.I know H would prefer me to be miserable too(he said so) and he has also said we should tell the kids we`re separating 'because we`re not talking anymore". That confirmed for me that he wanted me to be silent too so I`d be as guilty as him for breaking the relationship.
