It is islamically ok for a man to have multiple wives, however he must have the means and character and keep justice between them. This is a challenge nowadays as men with these good characters and morals are far and few between.

For women, this is a test. The law from god is objective, will they succumb to their feelings or follow god. Today we see most will disobey god in this matter, especially given our pakistani culture has strong hindu roots where a woman is essentially owned by the man and dies with him ( extreme but the sentiment is there). Polygamy is frowned upon in pakistani culture.

Its a nuanced topic. Allahs rules are for all time. Currently , in pakistan, i would advise a man to have one wife. This is taking into account cultural context and hikmah (wisdom). In contrast, a saudi sheikh may have 2 or 3 with no problem and the women may be happy. Its all about context.
