insta fold with overpair 25/50

[ShortySaurus]

25/50, 5 handed I am SB, villain is BB. Villain is the tightest player here and pretty straight forward. He just won a big pot the previous hand when he flopped a set against an overpair and basically doubled up. Villain has 5000 and I have him covered.

Everyone limps, I make it 500 (yes i know...a bit excessive) in the SB. Villain minraises 500 more to 1000. Everyone folds. Hero calls.

Hero checks, Villain bets 2000, Hero instafolds face up...

standard? besides the excessive raise preflop, does anyone do anything differently?
