How do you define “extremes”? I came home beaming from the first date with my husband and felt pretty sure this was it! Obviously, my family thought I was nuts, but they saw how happy and sure about it I was for the six weeks of dating him, so it wasn’t a surprise that we were engaged after six dates. B”H, not a second of regret more than a decade later.
There IS a concept of a neshama identifying its other half.
