1. He's infatuated with her.

2.  He hasn't figured out what YMMV means.

I reckon he just aint getting good milage on his sparkin.   I am a thinnin that if'n he went to all that time and trouble, gettin all in your face and hers bout thangs, that she is probably a reading him just about right.  Maybe he done hit her DNS listin thang.  

Before I moved to Carolina's
There was one guy I saw one time who would harrass everyone that reviewed me for details, he would publicly debate my reviews.
All over one service I did not perform with him, he felt he needed to debate every review for the next 2 years.
Seriously!
Sorry but demanding services, being nasty and an obsessive jerk will not get you a romantic experience.

He didn't have good hygiene. Maybe he was obnoxious. Maybe his breath smelled. Sometimes one guy just clicks with a lady and another doesn't. He should be asking himself why and not you.
