AKs hand- should I have been berated?

[octop]

1/2 Party and I'm in the SB with AKs and everyone and there mother limps in so I make it 12 to go ( 8 limpers)
UTG makes it 30 and everyone folds to me
To start the hand I have 120 and he has 130. I almost folded the hand (I have 44 hands with him his VPIP is exactly 50 and he got most of his chips hitting 2 pair after calling a 10 dollar riase with K2s) but when I counted up my 12, the dead money and his 30 there was 44 dollars 48 dollars in the pot so I decided to call for 18 more.

Flop is Ace 7 3 rainbow I check he makes a 20 dollar bet which screams trap or a feeler and I just call. The turn is a 6 putting a second spade on the board and I bet 50 he says "you lucky [censored]" and goes all in for 35 more which
I call. He has KK and I double up.

Did I play this wrong?
