Good aggressive play or just plain manical

This had been a very loose table w/5 or 6 callers seeing the flop. I thought there was a very good chance I'd get the limpers I needed so I limped as well. The button raiser has very lose raising standards. He would raise anything from a medium pocket pair to A8o.

I didn't want to bet out b/c I didn't think I could get everyone to fold for 1 bet. The bet came from the button so I thought maybe overcards, A high or a middle pocket pair like 66 or 77.

Turn(11 BB): 7[img]/images/graemlins/club.gif[/img]

Hero bets, Button calls

Went for the bet again in hopes of folding him.

River(13 BB): 5[img]/images/graemlins/spade.gif[/img]

I figured that if hes not folding on the turn, he's probobly going to just call the river.

Did I waste money by playing too aggressive or was this just a case of good play and a bad outcome? Should I have bet the river in hopes of a fold?
