PP 5/10, Overcards and draw

[Lobtec]

Fi in this case is 75/19 and 1.13 post. I have a little over 100 hands since we sat but havn't played him before. He calls down a lot and seems to be on tilt. He is currently about 30BB back.

Final Pot: 15.50 BB

He has been calling with a lot of hands and there is a chance that he has hit something on this flop. I choose not to 3-bet. At the turn I check to se if I fill or hit as I don't think I will get him to fold a raise or bet as I (and other) have tried this before. I also figured that if I get the flush I probably have an extra bet as he doesn't put me on a draw.
Well, the question. Did I play this to passivly. Sometimes I both 3-bet and bet out on turn with these kind of hands but right now, with the read I figured I was better of passive. What are your standard play? How would you have done with this read?
