What went wrong in my poker hand?

I'm in the big blind with AA playing 3/5$ no-limit holdem. I got about $600 in front of me. Everybody folds to two spots behind the butten. He raises it 25$ dollars. Now he is the big stack at the table with about 1500 and he is a loose aggressive player that has been calling every bet and has rapid changes in his stack. Basically hes the bully at the table. The action gets around to the small blind and he calls. Now I decide to slow play my AA and trap this super aggresive big bully and so I smooth call. The flop comes 4 6 8 with two spades. I check, again I know bully is going to bet. Bully bets 50$ and the small blind calls. The pot is now 185$. Now I decide to spring my trap. I raise it 150$. After a long thought bully calls and small blind folds. The turn is a 7 with no completed flush. Im not concerned with a straight because I don't think at all he raised with 910, 59, or 35 it doesn't fit his mo. So I bet another 200$. He puts me allin for my remaining 200$. I call because I'm very much committed. The river is a 4 of spades completing a flush draw. Bet you will never guess what he has. He has 77, trip 7's on the turn, wiping me out. Where did I go wrong, someone tell me?

I know what went wrong. Bully got lucky on the turn. But on the brightside, if a 5 would have came you woulda been drawing to two outs for only a split when you put in ur $400. At least the two outs you had were for the whole pot.Raise preflop for sure, what's wrong with making it $80-100 to go? I know ur opps would have hated it, and would prefer you to only call.If they fold big deal - It's better to win small pot than lose... Maybe you do get called, $200 bet the flop and hope they keep calling you with 7 outers. Not saying this play would have worked any different tho considering, 468 is a pretty nice flop for 77, I think you woulda needed to go all in for him to fold.
