Truth is, you don't need do go out to have the best Valentine's Day, actually, the best ones are celebrated at home. Here are some ideas:
Fondue night
Candle lit dinner, that you can cook together
Movie night: 50 shades of Grey,
Couple's massage. Get those candles lit and the massage oils ready for a steamy night.
Cheese and wine night
Bottom line is, it doesn't really matter what you do, if it's fancy or not, what's important is to make a little effort to spend time together and celebrate love!
