unless you've been in a healthy relationship with decent boundaries you're just doing trial and error. i'm not saying it's impossible to learn but you'll waste a lot of time in the meantime.
It's been said, but worth saying again: trial and error is life. Everything we learn in life, we learn through trial and error. Want to learn that the stove is hot? Touch it, and you'll have learned. It starts when we are born and continues through until we die. And yes - it's possible to spend a lot of time trying to figure all the life-shit out. I'll say spend, not waste, because until there's a instant-knowledge pill that you can take to learn anything you'd want to know...then some shit just takes time to learn.
We seek out the experiences and thoughts of others in order to help us find our way.
they still had to be able to learn but they didn't have to figure it out all on their own.
I honestly don't believe this is true. In my experience, there are things in life that we need to learn for ourselves. We might have the best family in the world to model off of, but we will still follow our own counsel....that's just a human being thing.
Besides: there are very few absolutes when it comes to living life. One person's hard boundaries may be another one's grey area. So, you cultivate what you think yours are, based on what you want them to be. And when you don't know where to start, you ask other humans what their experience is. And even then, you're still going to spend time trying to apply all of it.
You asked
@Justmehere for ideas:
what would those be in your opinion?
And justmehere had already given you a pretty solid one, about a page earlier on the thread:
Declaring it to be impossible to change negative core beliefs is how one perpetuates the false core belief and cognitive distortions. Choosing to instead to start challenging such negative self is the first step. Try using the search bar for “challenging cognitive distortions” and you’ll find lots of great info on this site about how to do that, and many trauma survivors who are doing it.
(I bolded for emphasis).
Personally - I don't always recognize when I'm being disrespected or used. My therapist has been a useful sounding board for me, in that regard. Learning about cognitive distortion and core beliefs helped me tremendously.
