Once a romantic couple forms, we're more likely to look for more egalitarian splits of power and divisions of labor.
We hold our relationships to higher standards than we have in previous decades.

Compared to previous generations, today's heterosexual men and women are more accustomed to thinking of each other as friends on equal footing, even outside of the romantic realm.
Other research shows that those in friendship-based love relationships feel they have a highly likable partner, and that shared companionship is an important part of the love.

For those who are currently married, the rate was even higher.
Men and women had similar rates, while younger respondents were slightly less likely than older respondents to view their partner as their best friend.
