Yeah, I agree actually.Polygamy is a situation that can bring out feelings and behaviors in a wife that she never thought she had. Jealousy, anger, pain and hurt are emotions that block reason, promote insecurity, and open the door to Shaitan. This is all part of the trial of polygamy. The Prophet’s (saw) wives experienced jealousy between themselves. There’s even a hadith where Ali R was contemplating marriage to Abu Jahl’s daughter while he was still married to Fatimah R, The Prophet’s (saw) daughter. The Prophet said that Fatimah R and Abu Jahl’s daughter could not be married to Ali R at the same time. He stated that what hurts Fatimah R hurts him and he didn’t want her trialed in her religion. (Bukhari.) Scholars differ as to the understanding of this hadith but that one of the understandings was that The Prophet (saw) did not want Fatimah R to be trialed in her religion with jealousy from polygamy.
Bottomline it is human nature. And most woman (including me) would rather not be wife 1, 2, 3, or 4, but the ONLY wife.
But then the question arises what makes a woman (the few who are willing to go through it today) go into polygamous relationships in normal times?..perhaps it is money- we see women marring rich shaikhs, kings of polygamous relationships all the time. The wives of the shaikh of Dubai are one example, that wives, ex wives of the guy with 84 children is another. Perhaps it’s security. Or perhaps a lack of other options. Or perhaps they managed to find a man truly worth that kind of trial.
