All women become like their mothers. That is their tragedy. No man does, and that is his.

This quote is saying that all women experience the “tragedy” of eventually becoming similar to their mothers, but for men, this does not happen. In other words, women cannot escape their mothers’ influence, but men can. This may be seen as tragic because it suggests that women are more strongly influenced by their upbringing and that they cannot always be their own person. On the other hand, men are able to create their own identities without being automatically associated with their mother’s character and behavior.
