embracing love means also embracing uncertainty and vulnerability.

This is true, as is the rest of your comment. It is a complicated thing, love, and different for all of us. I suppose all the we can hope is that when it presents itself, the opportunity, we are ready for it, open and receptive...Perceptive enough to recognise it too I think. Many miss it because they're looking for something they are just not capable of seeing...you know, the can't see the forest for the trees, sort of situation.
