Too Weak with Q's???

[iceit]

Stats on villain 54/4 with a TA of 1.0
No real reads on him either except that he limps with all kinds of hand and will cold call raises with a wide range of hands.In over an hour I saw him fold to a pre-flop raise only once.
Knowing this, and how passive he is, I was wondering if this line with my Q's is too weak? Should I just call to the river or was it a good fold?
