I cant remember ours either but in my defence there was so much going on when we got together neither of us knew what date it was. We just know its the end of October
does he remember, if he does you can say, "Babe its our anniversary soon" and if he says "yes i know", you can say "i bet you don't remember" he might give you the dates without him knowing you forgot, and if he don't well that will save you on presents and cards.... Anyway Happy Anniversary somewhere in November
