Weak flop with QQ

Hi. I am posting this because some of my friends thinks this play was really bad. I disagree and now I'm asking here to see what you guys think.

The converter got a little messed up, sorry for that it is my first post [img]/images/graemlins/smile.gif[/img].
Party Poker No-Limit Hold'em, 100$ BB (6 handed)
UTG ($224.35)
MP ($104.76)
CO ($100.10)
Button ($170.70)
Hero ($70.40)
BB ($37.02)

Preflop: Hero is MP with Q, Q.

UTG calls $1, Hero raises to 6$, CO raises to $12, 1 fold, Hero (poster) calls $6, BB folds, UTG folds. SB folds.

Flop: ($26) 5c, 10h, 8d (2 players)
Hero bets $20,CO moves all in (88$).


Hero?

My reads on Villian is a TAG but I think he just wanted me to fold. I put him on AK/AQ but never a AA/KK. Perhaps this is a foolish play so please correct me.
