Megosztott hang

My brother invited me to his wedding. Said he wanted to fix everything between us. Said it wouldn’t feel right without me there. So I believed him. I bought a dress. Took time off work. Spent money I didn’t really have… just to be there. But something felt off. He never sent me an official invite. In the family group chat, everyone talked about seating… but no one mentioned me. Then my mom texted me something weird. She said, “Just don’t cause a scene.” I didn’t understand what she meant.
