Thirdly:

If a woman touches another woman with desire, that is haraam; if there is no desire, that there is nothing wrong with it.

Fourthly:

One of the rights that the wife has over her husband is that he should give her her own accommodation, and she has the right to refuse to live with her co-wife.

We ask Allah to guide us and you and to make us steadfast.

And Allah knows best.
