I'm a big sap....so, that sways my opinions, but...
I think Valentine's Day and anniversaries are important....more important than the holidays like Christmas when you gift everyone. These two are about you as a couple.
Because of that, I'd say go with something that is signficant not to you, not to her...but to the relationship you have.
Clear as mud, right?
I mean....when Scoote and I first started together, the beach became a focal point for us. It's where we spent our best time, where we walked, laughed, relaxed. It was (and is)
our place.
So, for our first anniversay, I got her a tide clock...it shows how many hours until low tide (the best shell hunting, and when we always want to be at the beach). It's not "romantic" to anyone else...but it fit for us.
So....what's your place? Or your activity? What do the two of you do that makes you smile and laugh and feel really together? I'd say think of that (whatever it is) and get her or make her something that celebrates those moments.
