I think I get what the article is saying. There's a perception that women are allowed to use the word "love" casually, whereas men are not. A woman can tell a guy she loves him in ways that say, "I think you're a great friend," or, "I care about you a lot," or, "I wanna have your baby." When I guy says, "I love you," it means, "I have a crossed an invisible commitment line and now consider you to be a suitable long-term mate," whether we're trying to be casual about it or not.
... I kinda doubt it since the conventional/traditional nuclear ****** unit seems to have been beaten to a pulp, thanks to modern progressivism. Yep, fathers are supposed to be there to make men out of their sons, however sadly, it ain't happening. (another topic entirely)
