The flop c/r looks like a made flush. So what kind of hand do you think Button needs to call the flop c/r? I would never have thought of checking the turn for fear the button makes a PSB. As played it clearly looks like exactly what it is: a flush draw (nut?) that missed. If you've got a nut flush draw that just hit top pair Button should be making a PSB to take away your implied odds and rep a made flush. Given stack sizes the Button should probably push. Your push is your only option as played. I'd have made a $300-$350 turn bet and pushed the river.
