"I wasted like half of my summer tryna hold on ur hand!" she was clearly mad at you and maybe she was right. you deceived her all summer and gave her the false sense that you wouldn't leave her

"I guess you don't understand..." a single tear appeared on her cheek and she looked really hurt

"You're telling me I can't even hold your hand! Guess what? Yes, I can!" she didn't want to be a secret anymore, you were hiding the relationship with her for too long already
