Aha, so it's men that you have a low opinion of! "All they care about is sex so they never commit so these women sleep with them in hopes that they'll have a real relationship but then the men never let it go anywhere, and all the women are competing over this small pool of sex-obsessed assholes." In which case a narrative blaming men is bang-on accurate, but IMO this is nothing like the majority of relationships, especially as you get further from age 20 or so...
"Live, try things out, settle down when you're ready to" sounds fine to me, since again, these groups of unhappy women and undateable men tend to be loud but I see no evidence that they're demographically dominant percentages. Way too many ... not-the-most-attractive... dudes out there getting married for the math to add up...
