55 - w/ overcards + flushdraw

Stats for Blondy 25/20 quite aggressive. I'd been raising his bb constantly.

I called pf because I'd seen him make some donky moves before and I was in position.

Flop call was half float half for value and to see if he'd slow down.

I was folding the turn, until he shoved basically. Nothing made much sense. Advice please?

Obv first post - fold pf.
