some1 explain me armaan's words

hey guys in sterdays episode armaan was reely over reacting...i didnt understand when ridhima said ki tumne mujhe pehle kyun nahi baataaya n then armaan was like kyunki yeh bathroom.water.soup,mera dress pehenliya n yeh sab now its enough??....i mean y did he say this all she wanted to b romantic wid him😉 n he was sooo rude...i hated armaan in this😭😭😭
