What should I do for my boyfriend for Valentine's day?

I haven’t bought into the whole VD thing in the past, but my boyfriend does. I know that he got me something (and I know what it is and its pretty awesome), but I have no idea what to get/do for him since I haven’t really celebrated. There’s a pretty big income disparity right now so he’s not expecting me to do anything big and expensive because he knows I can’t afford it. But I’d like to do something to show him that I appreciate him and the effort that he’s going to on our first Valentine’s to demonstrate that he loves me. Not that he needs to. <3 Ideas?
