Doctor, doctor, what's my EV?

[Spaded]

I'm not rain man, but i beleived at the time that it was +EV to push after the flop bet/raise.

UTG ($39.10)
MP ($35.35)
Hero ($48.50)
SB ($29.70)

Preflop: Hero is Button with A[img]/images/graemlins/diamond.gif[/img], 8[img]/images/graemlins/diamond.gif[/img]. SB posts a blind of $0.25.

River: ($114.05) 3[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(3 players, 3 all-in)</font>

Final Pot: $114.05

MP has Kd 9c (three of a kind, kings).
Hero has Ad 8d (flush, ace high).
SB has Jc Tc (two pair, kings and jacks).
Outcome: Hero wins $114.05.

I had 9 outs for the flush, 3 more for the inside straight draw, giving me a roughly 52% chance to hit the nuts (12/47 + 12/46). Actual pot when they both went all-in was $100.4 (I had the large stack and pushed), and so I effectively bet bet $35.35 (largest villain stack) to win $65.05 net profit.

Is that slightly negative EV because I'm betting $35.35 to win $65.05 or am i actually betting $35.35 to win $100.4?

Of course, there's always the chance of winning it right there, but those odds are not so great when 2 people have to fold.
