Did I angleshoot this guy?

[KaMiKazE]

I am predominantly a live player these days and normally make it out to the casino to play 2 or 3 sessions a week. I am fairly quiet at the tables, rarely saying much more than "nice hand" or engaging in polite small talk. I almost never talk while in a hand, but yesterday I did something that I had never done before and I could really use your opinion on whether or not I crossed the line here. Here's the situation:

Skip to post-flop action. I have A-10off on a board of 3-9-K rainbow. Villain leads out for $15 (1/2 pot) and I pop it to $40. He re-raises to $80. The guy had about $150 behind and I thought I had a read on the guy that he would fold to a shove, so I put him all in. I sat silent and motionless as is my SOP. He agonizes for literally 5 minutes and then starts saying things like "I don't think I can fold now" and "I'm a donkey if I lay this down." Basically, he starts talking himself into calling. I really feel like he is about to make the call when I do something out of character for me: I look at him at calmly say "I got you and I'll show you." He lays it down and I show him the bluff. He goes apeshit. He tells me I am an unethical "dickwad" and that I am a disgrace to the game, etc... I did not respond, but simply sat and pondered to myself whether what I had done had crossed the line. Thus, my question to 2+2 - Am I an angleshooting douchebag who should apologize to the guy next time I see him at the table or is what I did part of the game and acceptable strategy in trying to entice a fold? Thanks for your input.
