Cure for relationship winter blues!?

It's half term and im away on valentines. I called my bf this evening and asked if we could meet. Stuff's been pretty crap between us recently (not like arguing or anything, just not much contact) but i recon it's just a phase. We didn't talk much... Neither of us said anything about valentines. We'll probably meet next weekend and go iceskating or something. We usually get on really well with sparks flying but I always let my bad winter blues get in the way of our happiness. I want to re-ignite the spark but I'm not sure how and valentine's seems to make it worse coz it just adds pressure. Any suggestions?
