Think about it, how fucked does your relationship have to be to post on Reddit for advice?
Not to mention nowadays an untold amount of posts to subreddits that invite commentary are made up stories from accounts trying to get engagement.
Not that these relationships subreddits are good (often it's obviously children trying to give advice they don't have the experience for) but I don't think that telling people to break up more is less accurate advice.
"No one owns you anything, you don't own anyone anything" mentality, without a crumb of social awareness.
