I've got history with Valentine's Day, which pisses me off cos I think it's a load of shite so that adds insult to injury!
A week before the last one, I got a text "not feeling it for Valentine's could you handle just being friends?"
And years ago the on again off again love of my life (I thought) sent me a card with the wrong postcode and when he didn't hear from me on the day (I didn't want to scare him off as he hadn't sent anything to me) he called up his ex and got back with her. Which went v v badly. Pity 
There's never a good time!
Point is, I'm over them both, as will you be.
And you won't look back in Jan or Feb and think "wish I hadn't bothered fitting him in over Xmas".
I disagree with the bubble bath / chocolate / alcohol / chick flick types. Fine if that's your thing but it's a pretty boring thing to me. Get a babysitter and book yourself onto a indoor climbing course with your free time. Great fun, and you'll feel strong about your achievements when you reach the top!
