Meh: Questioning myself over losing value

[ajmargarine]

Villian buys in medium. Tries to play poker. Meh. He's got ~$50, I cover.

.50/$1 NLHE 5-handed

Preflop: Hero is MP with A [img]/images/graemlins/heart.gif[/img] T [img]/images/graemlins/club.gif[/img]. SB posts a blind of $0.50.
Villian calls $1, Hero raises to $4.50, 3 folds, Villian calls $3.50.

Flop: ($10) T [img]/images/graemlins/spade.gif[/img] 7 [img]/images/graemlins/diamond.gif[/img] 2 [img]/images/graemlins/club.gif[/img] <font color="blue">(2 players) </font>
Villian checks, Hero bets $7, Villian raises to $14, Hero puts Villian all in for $45 total, Villian folds.

He took a long time in folding, making me think that he had a ten. Milk it or 3-bet push in this spot. I'm going to the felt with this hand given his stack size and his previous play which was unimpressive.
