Weak tight play? middle pair + nut flush draw ($2-$5 B&M)

[KowCiller]

$2-$5 $200max at my local B&M

Hero ($525) is in MP2 with A[img]/images/graemlins/diamond.gif[/img] J[img]/images/graemlins/club.gif[/img].
Villain ($300) is in BB.

Villain took down one pot uncontested and he's only been at the table 1 orbit. He hasn't done anything silly and by the way he carries himself, he seems like a reasonable player.

Is my play weak-tight here?

Preflop: 2 limpers to me, I limp, CO limps, SB completes, BB checks.

4 players check to me, I bet $25. CO folds, SB folds, BB calls, other two limpers fold.

BB checks, I check.

BB thinks for a second, then leads for $50.

I muck.

Weak? Boring? meh?
