What does it mean that my girlfriend won't accompany me on Valentine's Day night?

I believe she is angry not because you didn't give her a gift, but because you only considered your own feelings and gave her a cold day on this special day. You don't have to give her anything good, but at least be considerate and stay with her. People happily go out in pairs. If you don't go to see her until evening, she will definitely be in a bad mood. Be honest with each other. Think about her, too
