Understand this is my opinion and is not stated to suggest this is how you should handle yourself...

There are always a number of different ways to handle things like this...

a 25th is a big one for many couples...

My own take and spin on this is, first and foremost, celebrate and honour it in whatever way you feel is appropriate FOR YOU...

Treat yourself to a pleasant day...

but...

if you feel it appropriate, make your plans elastic enough to include your H if he chooses or if he makes plans for the two of you...

and if your H happens to acknowledge the day to you, then respond accordingly...

as cadet suggested above... mirroring your H at this time is probably a great position to take right now...

oh, and again my opinion, but any time your H offers to do something for you, I say take it... just never do or accept anything with expectations...
