10 NL pokerstars

Coverter not working so ill type it out.

Vilian is CO Hero Is on the BTN.

oh and stacks ~100BB

2 folds CO limps I raise to .50c with QJo and blinds fold.

Flop 92Tr
CO checks I c-bet 3/4 pot
CO takes a long time then calls.
Turn other T still rainbow

Villian leads for 1/2 pot
WTF?
I know Im never ahead here but do I just give up?
I folded this hand but is a raise ever right here?
I have been getting into these spots alot lately dont like just giving up.

Reads villian 45/3/5 but only over 25 or so hands.

Whats a reasonable range for villian here A9 44-88? not sure

Why fold? You have OESD getting 3 to 1 immediately and you're in position. Call it and look for an 8 or a K.

oops edit villian bet pot on the turn maybe should have called just curious about how to respond to donk turn bets in general as well.
