First and foremost: get a pet. You will never wake up alone and you will never be loved more by anything else in the world. Here I am with Fanny. If only a significant other could look at me the way she does. (Fun fact: she is 100% blind).
Lastly: try to find something fun to do on V-day evening. I know jumping into sweat pants and watching the Snapped marathon sounds great, but try to muster up some social interaction. I am lucky and was able to wrangle some friends together for a night of pizza, wine, and other snowed-in entertainment. If you cannot find any dateless participants, simply refer back to suggestion #1!
