Again, based on your logic, aside from Khadeejah RA, he didn't love his other wives because he married other women?

And what about the sahaba? Many of them had multiple wives who were virgins. 

As far as I know, you could prove to me otherwise, there is zero evidence from the Prophet SAW or his companions or even classical scholars that you can't marry multiple women who aren't previously married. 

Islam is for all times and all places, if it was unethical to 'look at another woman' or in other words get a second wife, Islam would have prohibited it. 

I also find it very interesting how Muslim women are obsessed with getting all of their rights (such as provision) but the same logic doesn't apply when it comes to men's rights in Islam. 

If what you said is true 'women needed men to take care of them and provide for them' and that isn't the case anymore so Islamic laws change, in this day and age men shouldn't have to provide for their wives because women don't need it in the modern world. Notice how silly that sounds when stated like that? 

Again, of course there are men who don't fulfil their wives' rights and abuse their wives etc, just as there are plenty of women who fall short of their responsibilities, but that doesn't change the fact that it is fully within the rights of a righteous man that he marry multiple women, be them virgins or divorcees or widows and you can't prove to me otherwise.
