basically he has to have the means of treating you both equally, I.e, if the two wives live in separate houses than he has to give both same standard of living, quality of food etc
I suppose u can both live in same house but in different bedrooms, two wives can never share same bed with husband.
regarding love, he has to try to be equal with u both but love is not always under our control so he may find himself inclining more to one wife than another and he may spend more time with one wife (like sleep round her place) with the other wifes permission
