I found myself in a chasidish camp one summer (how that happened is a story in itself) and got to know a lot of very wonderful girls from very chasidishe homes. I really admired the camp mother and spoke to her quite often. She told me that she met her husband in just 3 dates in one week, and since her parents did a lot of info beforehand this was enough time for her. She told me that in her circles they meet a minimal amount of times and this system works very well since they do thorough research before the boy and girl actually meet.
This is not something to debate if you think its right or wrong, point is, pple do it and it works for them.
