Something simple. A card and/or some candy. Nothing too eloquent.
A small gift/card would be appropriate after 7 weeks. Completely ignoring the holiday would be like ignoring that you're together.
You seem sweet, mind if I lick you to make sure?
If he genuinely doesn't know it's Valentine's day because it is a week day, then trust me, you do not want to keep this one. If he doesn't come and see you on Valentines day, you still don't want to keep this one. In my opinion saying "No Valentine present, no blow jobs." would be a complete waste of good breath.
I really hope he surprises you sweetie,
I wonder how this turned out!
I've come back to see if she's answered.. I have a feeling we're going to be disappointed folks..
