How many people have been wife-/husband-potential before you met the one you settled with? (26M)

Had a break-up some months ago, and she was basically perfect. I don't have a body type myself, but she was thicc, red-haired and had green, big, beautiful eyes. And that's only the package. Her personality was miles ahead even. Active, motivated, engaging, happy, bubbly... let me cry in front of her and consoled me. Did everything to help. Reeeally loved me. And I let it slip due to complacency and lack of motivation. Ofc there's two people to that, but I was an asshole, let's be real. She wanted me to quit weed and get my life together, and my daft ass couldn't take it. Had to make excuses or outright dismissed the possibilities. And then one day she says she just can't anymore. And then she broke up after 3 years of dating, 2 and a half of relationship. Fair enough on her part.

Now I am amssively afarid to never meet someone like her again. I know I won't, thats the fun part of it, but maybe someone else worth again. I feel like she was a once-in-a-lifetime girl. A real unicorn. And who meets two unicorns in one life? Please share anything, good and bad. I want to keep it real. Did you ever lose someone on your behalf that was a extraordinary fit, got broken up and then found someone else or even better? Or are you still searching for that person?
