I'm not the romantic type either, but I'm inviting my BF over for dinner and I'm making him a nicer dinner than I would normally make, just because it's a fun thing to do. Putting pressure on yourself to do something spectacular for such a ridiculous holiday, like Valentine's Day, seems unnecessary to me. Just spend time together and enjoy the day, don't put so much energy into thinking it has to involve grand gestures, when you should be showing your partner you love them every day.
