Valentine's day girlfriend is not around, how to send her a message and ask about the content of the message? ...

The first sentence is mostly what you usually call her. Since it means what you miss and care about, what is the main content? See where your relationship is now. I'm sorry I can't accompany you during the holiday, but it's up to you. Actually, just write down what you want to say to her. No matter what you send, I think she will like it. Writing about your heart is the most important thing. Others can do very little, but it will be your business.
