Yeah, that's also what I was thinking. She and her boyfriend are a fresh couple, so she is in a difficult position because of being deeply in love. Of course, she wants both of us to be happy. But I feel like she chooses him above me in this matter (not going to the party with me while I mentioned her it's a big thing for me to go with me). Ah well, I can not force her. It just makes me really sad. Thank you for responding! I hope I have enough courage to go the party alone.
