Oomis +1.
DY, I don’t have the statistics but out of the people that I know there are pretty much the same amount of married and unmarried girls/boys who follow shidduchim as the poster discussed, and those who date more like oomis is saying. I will say that my friends who followed the shidduch rules much stricter, dealt with much more frustration, dated way more guys , got turned down a lot more, and many were in shidduchim much longer.
Both my parents and my husbands parents, granted they are more modern them the folks on this site, both met each other at frum singles events run by either their shuls or JCC type community centers. That’s how many of my parents friends met their spouses.
My husband has a friend who got married bH last year, but he dated for 7 years! He had resumes piling up, went out all the time but was awkward felt that the girls weren’t for him, were immature, had no social skills, and they were both uncomfortable in the environment expected of him. He ended up going to college, relaxed a bit, he is still a frum great guy, learns and works, but he ended being set up by a friend ( shock) and they dated a bit and it was great. I know that texted after sometime and didn’t use their shadchan past I believe 3 or 4 dates. They were able to be adults without their parents and shadchan overseeing every detail of their lives. They are happily married parents now. My husband and I had a similar situation. Not everything works for everyone and I feel like shidduchim have to room for error or adjustment and no one seems to realize that it’s not one size fits all.
