Read it through once

"You speak very properly. Willoughby certainly does not deserve to be suspected. Though _we_ have not known him long, he is no stranger in this part of the world; and who has ever spoken to his disadvantage? Had he been in a situation to act independently and marry immediately, it might have been odd that he should leave us without acknowledging everything to me at once: but this is not the case. It is an engagement in some respects not prosperously begun, for their marriage must be at a very uncertain distance; and even secrecy, as far as it can be observed, may now be very advisable."
