Just look at all the threads! If it is really important to you that your DH is romantic and vice versa, shouldn't it be all year round?
We aren't what I'd call romantic but a couple of times a year I get flowers from DH or I take him out for dinner etc. I just don't understand why it has to be on a set day?
It was important to me when I was 16 and undoubtedly NOT getting a valentines card from anyone though. I'm not entirely sure when it changed but I'd reckon by 18 I was over it.
