RE:It’s interesting b/c in the chassidishe circles there are so many older boys and hardly any older girls…
Possibly because in Chassidish circles boys who go to work before marriage, are much less desirable (very few Chassidishe girls want them) than working boys are in the Litvish world. So in the Litvish world, the learning boys get grabbed up, but working boys have many options as well. This leaves Litvish girls who aren’t the most desirable, with very very limited choices, and therefore many are single for a long time and many stay single r”l.
