Maharal: Wife easily hurt if not treated as equal

Maharal (Bava Metzia 59a): Rav said that a person should always be carefully not to oppress his wife because she is sensitive and readily cries so it is easy to make her feel oppressed. Thus we see that it is only his wife that he needs to be exceedingly careful not to hurt her feelings since she is ruled by him and therefore is much more likely to cry than other people who are not so easily oppressed. In other words because his wife is under his control she is more likely to be hurt by his words and cry when he wrongs her. In contrast a non‑Jewish slave is by nature not so affected by oppression and even a female Jewish slave does not readily cry because she has accepted the servitude to her master. Furthermore a female slave was not created for the purpose of being under his domain. It is only the wife who was created to be under the rule of her husband and as it says (Bereishis 3:16), And he shall rule over you. Therefore when she is oppressed it has a very strong impact on her. Furthermore in truth a wife does not accept being ruled by her husband because she views herself as his equal. In contrast a slave fully accepts that his master rules over him and therefore is not impacted as much as a wife who views herself as important and therefore is devastated when she is not treated with care.
