NL10, button-sb-bb unraised pot situation - should i be as agressive?

[Winenose]

Played just some hands after work, had no reads. We all had about $8 in front of us.
I didn't want to raise preflop - this table was rutinely calling up to 5BB with all kinds of hands.
Should I fold the flop? I had not invested anything and wasn't getting immediate odds, come to think of it.
Anyway, I probably should have check/folded river because he lead the flop and called my turn bet?
