Tough spot - need help

[Xexilla]

Hey it's not that tough a spot but it's a situation I am running into regularly... Should I just fold to his bet?? Raise then shut down if called or reraised?? or float and reevaluate the turn?

It is just a small bet I hate folding here but this situation is happening way too often and I find they often have second or top pair.
