Given you mistakenly cbet the flop I think your line is fine and the turn is an easy fold. I don't think AJ is strong enough to call a 3bet pre flop and would have 4bet/folded over flat calling read-less.

Deep and oop you're going to have a tough time making AJ profitable vs an aggro opponent. I'd go for a fold pre. I don't think a 4bet is going to be particularly good because of the stack depth and he can just call a ton of hands.

Sucks that you misclicked the flop, I think that made this hand way harder than it should have been. I recommended line would have probably been x/c x/c x/f of course depending on runouts. As played yeah I think call flop and fold turn is a reasonable line.
