Perhaps I am the exception.
Yet you guys act like romantic relationships evolve in a bubble shielded from real life.
I personally see them as little more than improved friendships; I look for exactly the same qualities in SOs as I do in friends - plus physical attractiveness and sexual compatibility. I'm extremely introverted and quite busy, so I don't have the energy or the will to just make mistakes over and over again with my friendships. And if you do pick your friends wisely, you learn a whole lot from them. Same about family.
You DO learn when to get out of a ****ty/destructive relationship, to take notice of toxic behavior, to speak your mind freely, to admit when you're both simply not compatible, etc. And you act in consequence.
Sure, it's not completely like having a boyfriend/girlfriend. You're more head over heels generally, and it can be harder to see the big picture and let go, etc. There are criteria - like an emphasis on personal responsibility, at least for me- which you may not have applied to your friends, or to a lesser degree. There's a lot of unknown.
But you guys make it sound like a romantic relationship is the same as walking into Mordor or something.
It really isn't. If you've been leading a productive life on the personal plan, at least (I'm not saying that you haven't if your first relationship has failed, even spectacularly like fancy. **** happens!).
Ofc if you have your first relationship at 15-16 y/o or whatever like most people, you haven't time for personal growth yet. What do you expect, then? Of course your relationship will likely fail. How many people are you still friends with/can still smell from high school? Not many, I'd guess.
And try to genuinely reflect on the people around you. Have they
really learned from their relationship mistakes? In my experience most don't - they keep dating these "badboy" guys who treat them like ****, or they always rush into another relationship after the previous one crashed and burn, never taking time to reflect, etc; and those that do learn have seen that spurt of maturity in most areas of their life, not simply romance. But that's just my experience, I guess.
And
@Kaustikos: casual dating for me was the biggest waste of time. Still is.
Sure, a first date to see if you're both compatible at first regard is important. But dates after dates for the sake of it? Jesus. I don't see what anyone could glean from that... except becoming "better" at dates I guess?
