The Devil card often brings a harsh honesty that points right to the dark side of a topic, even something as light and fun as Valentine’s Day. The Devil card can make you angry and defensive in a heartbeat if the dark one strikes close to home.
Valentine’s Day is just an excuse. If you use it as an excuse to do something thoughtful or to show your love, the act and the feeling is what really matters, not the day. If you allow an arbitrary “holiday” to impact your mood or how you feel about yourself, then that is your choice. It is not about your soulmate (or lack of one) no matter what day it is.
