Hmmm, why not go on a weekend break to somewhere in europe.
i know its sounds corny, but he will always remember your anniversary and remember what you was doing on it...
plan something together, because one of you may be disappointed if one makes more of an effort than the other. neither do you both want to plan some suprise and it clash. mention that the anniversary is coming up and ask him what he'd like to do. was there anywhere you went when you first started dating, or something special you did then?
How about a tour round his fave footie ground or somethin you knoe he's always wanted to do. If not that then book a night in a nice hotel and spoil yourselves rotten ;)
Not all blokes dont remember it!!
Me n my fella had been together 3 yrs this march and he gave me the most gorgeous, silver, mother of pearl & diamond watch! :)
