Sucked into a flush. Was it wrong to call?

So this seemed like a big mess to get myself into. Was it wrong to keep calling the raises? I figured with a pot that big hitting third nut flush would still be worth it since each bet that came to me was always the right odds. What do you guys think? Should the paired board worry me?As for the PF raise, that was mostly an attempt to buy the button. Thanks for input.
