I dont understand why will women have to stay indoors in jannah?

Isnt Jannah a place where all inhabitants cant commit sin so why do the women need to be 'guarded' and why do we have to stay inside???

Does it mean we won't be able to meet our family members from this life??
Does it mean we won't see our children?
Estaghfirullah but this is the one area as a revert i still really struggle with and i have to be honest i dont like the description because it doesnt seem fair.

Estaghfirullah it really upsets me.
