Our time-lines sound familiar too. My H had just ended A #1 and was just getting "more than friendly" with OW #2 when it was our 10th anniversary last May.
And I wondered why he was so quiet during dinner, why he wasn't more excited about the sapphire rings we exchanged (all my impetus, of course. I shudder when I recall the jeweller commenting on what a sweet couple we were, how still in love after 10 years... , How did H pull it off??).
Ah well, I think, no I know, that this funk you are in will lift some, J. I was in the pits for most of last week and now I feel a bit better. Just made a lengthy post to LL re the whole "physical touch" thing, seems lots of us are feeling down about it.
