AITA for asking for the $600 back in writing after two years of hints?

lent it to a guy i've ridden with since 2019. he was between jobs, i had it, i didn't make it a thing. two years. i've brought it up light three times. finally sent an actual ask. he replied like this.
What People Are Saying
the favor ledger comes out the second the money ledger comes out. always. moving somebody is not $600.
"I'll see what I can do" is a no that's trying to buy six more months
that's what my wife said. she gave it until christmas and i think she's being generous.
NTA and write off the money in your head now. you'll either be pleasantly surprised or you'll be at peace.
the transmission detail is what gets me. you had a real reason and he still went to the ledger.
Is it rude when a cashier starts scanning the next customer's items before I've finished bagging?
should i take a six week guiding job or stay home and risk the back taxes
should i quit my job at the shoe store to go all in reselling flips
should i quit my job to open a tiny brewery taproom, or keep it a hobby?

"this is exactly why I don't borrow from friends" while owing a friend $600 for two years is genuinely incredible framing
