A. Your first concern is no different whether matching a divorced guy with a divorced girl or a divorced guy with a never married girl or a never married guy with a divorced girl.
Do you generically worry any divorced girl may have been abusive?
C. Who said he’s davka looking for an never bmarried girl? He may be open to a previously married girl or a never married one.
Additionally, according to Jewish tradition there’s a positive benefit to marrying a never married girl. So that is a good train he may be looking for such. Furthermore, it is a positive commandment to have children. That may be another reason.
The Chofetz Chaim and the Ribnitzer Rebbe, to take two recent examples that come to mind, married young never married women when they were in their old age. And the CC had more children.
