It is better to hide her from the first in order to have peace and keep your first marriage if he really needs to have a second wife (instead of doing haram he marries and do halal nikah)…. Allah gave the husband the right and permission to marry up to four women so the females should not be asking him not to remarry… I am a woman 👩🏾 and I am all for polygyny and I want my husband to marry again if he wants to.
