how to handle agro player to my right who might be trying to run me over

At a 5NL full ring cash game, I'm seated directly to the left of a fairly aggressive player (~22/15/3 over 20 hands) for about two orbits and watch him steal a blind and make a couple of large bets on flop, but nothing completely crazy. I play three hands against him in total.

Hand #1: The first hand he's seen me play, I raise in EP w/ a decent hand, it's folded to him in the BB, he 3bets big, and I fold.

Hand #2: Next orbit I'm in the BB w/ AKs, it's folded to him in the SB, he opens 5xbb, I 3bet, he shoves, I call, he flips over AA which holds up.

Hand #3: The very next hand, I auto reload in the SB w/ AJo. He's got +250bb, it's folded to him, and open shoves....

Is he trying to run over me? Do I call? There's a super nit (9/6/2) to my left in the BB who folds every steal. I don't have a lot of hands on the villain, hardly any steal stats, and no other reads. Do I call w/ AJo?
