While it may be true that chassidim have a lower rate of singles, I wouldn’t say their method of dating is more successful. I have friends who are chassidish. I’ve heard from them many times how many chassidish couples are unhappy in their marriages, but won’t consider divorce because of the stigma attached to it in the community.
Some women also have a twisted view of what marriage should be. When my wife gave birth to our twins, she was next door to a chassidish woman who had also just had a baby. They used to talk a lot. The woman commented one day that she was so happy to be fulfilling the only purpose of her marriage properly. My wife asked her, “What do you mean, the only purpose? You think having babies is what your marriage is about?”
The woman replied, “Of course, what else would there be to marriage?”
“Well, how about a relationship between you and your husband?”
“No, that’s not the purpose of marriage. It’s only about having children!”
“So, when you get into your 40s and can no longer have children, you want your husband to divorce you and marry an 18 year old who can have more kids?”
“Of course not!”
“So there is more to it than having kids, right?”
“Umm…. I need to think about things some more.”
My wife told me she felt bad, and almost like she was “corrupting” the woman. I told her she was undoing the corruption that the woman had drilled into her since her childhood.
