Your girlfriend is really lucky I must say, cause your kind of person are rare. It is usually had to see a guy who will talk to his girlfriend politely or will even want to listen or ask questions in order to know why the girlfriend is nagging....

It is very true that all genders tends to nagg in relationship, but then women are mostly found nagging than men in relationships. And the way to stop or reduce nagging in every relationship is that, both parties involve in a relationship should ensure that there is effective communication skill and mutual respect amongst them as you have rightly stated.

Best wishes🙏
