Should I have seen this coming?

This is my first posting of a hand that I played. I am new to poker, but not totally new that I have no idea what I'm doing. I just started taking poker seriously, wanting to enjoy the great riches that it can bring (within time of course).

This hand was not from a 6-max table although some people folded it to make it short-handed. Also, I am under a new lead so this is where I'm supposed to post.

Should I have seen this coming and folded back on the turn?
