I don't know if I agree with all this advice. If a guy came off like an jerk to me, I'd be really offended.

He doesn't say 'act like a jerk. He pinpointed what 'nice guys' often do (such as buying gifts or giving unreturned affection) that they think is nice, but does not work.

Dogging behind a woman that doesn't like you isn't good, but I see nothing wrong with respecting a woman and giving her gifts.
