Need help?

Me and my boyfriend got into an argument because we were in my car and I was driving and he asked me to roll up the window so no one sees his face and I told him my AC don't work and it's hot in here and he goes idc roll yours down. Then starts being persistent to roll the window up so people don't see him. I took it offensive and hurtful and was basically thinking he didn't want someone to see him with me or he has another girl and don't want that person to see he has somebody.am I wrong for being mad? Cause he got real offensive and hype and called me paranoid. But I just told him how it came off that way.
