Addiction to porn and easy access to low tier content/hook up apps is killing relationships. I think the effects of birth control on women's partner selection has also not been studied enough, though there is evidence to suggest that when some women get off birth control they lose all attraction to their spouse/significant other.
In general I'd say the cultural decay of the west is impaling relationships as it is all things.
This is like a copy pasta from a 4chan incel thread. Someone has been blackpilled.
