Not sure to understand the question? How could you not know?
If you're thinking about finding the 'perfect' partner, forget about that. It's a lie. It's something fabricated to sell ads, page views and subscriptions to shitty services. Nobody (including you and me), nobody is perfect. So, no relationship can be perfect.
My spouse and I have been together for 25+ years and counting. It was quite obvious very early on we're fitting together nicely but that was far from being a perfect match and we had a few rough times and, all those years later, we can still have. But we've quickly realized how lucky we were to have found each other, and we valued that enough to get over any difficulty or hardship. And we still do.
So, to me that's a 'right relationship', just not 'the' right one as we could as easily have both been as happy with someone else if things had been different ;)
