Semi-Deep Heads up facing river push

[Greeksquared]

I never post but found this hand to particular peculiar. Villain is tilting a little on me and telling me how horrible I am at this game. He has been fairly aggressive and check raising me fairly often. I have no idea what to put him on here.

I start the hand with about 150 and villain covers. I get dealt A3dd in the small blind.

Villain raises to 3 I call

Villain bets 4. I CR to 10 he calls fairly quick

I bet 25, Villain thinks for about 10 seconds and pushes. About 80 more to call

I really don't know what to put him on. Help?
