NL200; Folding bottom Set on the flop??

[frankpark9]

BB is a donk and i have never seen him 3 bet since i sat down at the table so i put him on a big pair or aq, ak.... i was planning to get it all in with him. but when original raiser shoved all in it got me scared there... he's 150bb deep and his stats are 19/16 over 2k hands, me and him have been 3 betting ALOT on the other tables. there's one hand where i 3 bet with 1010 and he cold call with AA and the flop came 10 high and he CRAI and lost with AA. do you guys think this fold is good in the long run?
