Damnit...feeling confused with trips

[RiverFenix]

From memory.
Villian just sat down and is BB and i cover UTG, 5 handed 100 nl 6max
I have villian in database and weve played together a few times before he is way aggro, but a bigtime winner but I have no notes

I call with QJo, folds, villian checks
Flop Q 10 4 2-flush
Villian bets 3, i call
Turn Q
Villian bets close to all in, Hero...?


I was having an extremly good session and felt like this was the most important hand in it. Easy call? I thought about it for a long time since Im guessing he knows me and since he is quite good from what ive seen
