Final Pot: t5360

Oh well, guess my line is not very good here.
I guess it's push or fold on the flop after he raises, right?
Folding seemed to weak..
But calling can't be the right decision, pot will become very big anyway.
Any clues appreciated.

€: I guess i should have bet the flop for like 450 or more cuz it's very drawheavy, am i right in this assumption?
