in my view
mujhe gussa dilaya gaya . He was already vulnerable , and wanted someone to hear his problem and his pain. His career and life was stake. But she brings food for him. He says no. Don't bother him. Be silent. Give him some space to open up. But you start argument with not eating breakfast and pakhi. Any normal person will get irritated. Yes Sai does overreact at times. And it was she who provoked him this time.
For second I do agree with your analysis.
