Did I play this AJ wrong

[gmcarroll33]

1/2 No Limit game. I've got about $250, guy I get involved in the hand with has about $200 or less.

About 3 limpers in, and I'm in late position with AJ Spades. I raise $10 get called by the guy with $200 who has AK. 2 of the limpers call making it a $40 pot.

Flop comes AK8 2 spades. Checked around to me and I bet $20, guy with AK raises to $50. I really thought I was okay here because I had a 4 flush and top pair with a pretty solid kicker. Everybody folds I call. Pot is $140.

On the turn a blank hits and he goes all in for his last $150 or so. Basically he overbet the pot. I'm pretty sure I made a horrible call here, but I couldn't see the AK because he limped with it on the button and thought my AJ might have a good chance, like he maybe had A8 or K8 and I could pair my Jack and win with a better 2 pair or even hit the flush. Anyways I called the $150, and hit a Jack on the river to make 2 pair but lose to his 2 pair of Aces and Kings.

So with top pair and a flush draw here with a good kicker, was this an awful call? I feel it was, because before I called I told the guy that if I was about to put a bad beat on him I was sorry. Bad thing is I think I was going to lose all my chips on the river anyways if he still had money left.

Was my call as bad as I thought it was at the time, or not good but not terrible, or alright?
