Occasionally people here get into discussions about social relationships, namely dating, and what quickly comes up is how both of those seem to be less common and harder to 'get'. This more frequently happens in overtly dating and relationship subreddits and similar dedicated spaces, albeit, of course, this also pops up in more general communities, alongside any community where social relationships are an important topic, like communities about social ideologies like feminism or the manosphere or about genders because heterosexuality.

One thing I often find is missing is some historical context. A lot of talk about loneliness and lack of platonic or romantic relationships is basically limited to the recent past, if it even talks about the past at all. It seems like it would be helpful to look at what relationships and dating were like 10, 20, 30 years ago when it comes to talking about the problems or just general state of both today. So do you know of good sources of information concerning relationships in the past? If so, then why do you think they don't pop up in discussions about dating?
