I don’t know that I agree with this….
In the first place, we have to understand that “perfect" relationship means perfect for you.
That requires knowing oneself. Doable. It also requires an open and honest partner. Also doable. It requires respect of boundaries from both parties. Doable. Investment in both the partner and the relationship itself above oneself AND expectation of the same in return. Doable.
And so forth and so on.
It’s completely possible.
That said I recognize the difficulty in getting there. I have not been successful myself. But, I don’t think it’s because it’s too hard, or nearly impossible. I think it’s because weve stopped training for it. Used to, people spent a lot of time in reflective thought about such matters. They read about it. They discussed it. It mattered profoundly as a cornerstone to their future happiness.
We don’t do that anymore. We watch TV. We play games. We can’t sit with ourselves anymore.
So, if we never come to truly know ourselves, how could anyone else either?
