You know in reading this, I’m torn between shaking your hand and slapping you (in the arm) because I have met and known guys like you. I worked with one who screwed me, I warned him, and then he subsequently got screwed by the person I tried to warn him about.
I don’t see a guy who doesn’t know how to relate with someone who can’t pay their bills. Nope. I see someone who forgot what it was like to be 10k in debt with $200 in the bank hoping his idea worked. Then when it did, he considered himself beyond all of that as he drove off in his Tesla not bothering to look behind for fear that he may see what he was leaving behind. Hubris is a helluva drug. I don’t think you’re an asshole. I also don’t think you’re off the hook either. Humility is a hard, long walk.
I am happy for your success because you earned it. I hope you take care of it. But, in reading your post I had one question that I can’t ignore: did you try to mend the bridges you busted or are they ash?
