My child was upset not because of the rejection, as you say that’s all part of the process but because they were used. Double daters do indeed sit there and see which offer is the better and then drop one and date the other.
This is my last post on the subject. Date one person at a time. What’s the big deal so you wait a day or two for the next one. I think people’s feelings are more important than double dating, comparing or whatever you want to call it. Life’s not that short that a shidduch cannot wait one extra day.
The end.
