“This simple tactic has been extremely effective in the last year. Any problem with it?”
Personally, no. But I have many friends who do. A lot of people specifically want to marry a girl thats a few years younger then them for certain reasons. And frankly, I can understand that very much.
Additionally, most people see it as a negative if the girl has been going out for a few years and still not married. Is it just because they haven’t found “the one”, or is there something that I don’t know about? Many people don’t want to take the chance.
If Hashem wants me to get married he’ll send the right girl when he wants her to come. Same thing for girls. Let’s not go jump and get people to go out with different people then they would “for the better good”.
And by the way, one of the big reasons why there are more girls then boys is because it’s much easier to be a “frum yeshivish” girl then a “frum yeshivaish” guy. So you have much more guys that people in the frum community won’t want their daughter to go out with then girls.
