odd thing... my 10th anniversary, was also this year. august.
I presumed it was going to be another total bomb, like last year. (separated then also)
but... I decided "what the heck", and invited my wife to dinner. didnt mention anniversary in the invitation. and she accepted. and we had a pleasant evening.
(and it seemed to be a small turning point, in things being slightly more positive between us, rather than negative)
From my perspective... when I invited her.. about the worst thing that could happen was that she said "no". turns out, she said yes! but if she had said no... i would have survived.
Just let things happen. If he says things you dont like... just ignore him. If he says nice things.. then thank him. If he says NOTHING... well, then you'll get your "wish" for nothing happening for your anniversary anyway.
I think you will regret not even allowing the chance, though.
