Can someone help me understand why women are looking for a platonic partnership?

I know this is a bad question all together.
I do know there are asexual people.
I have two female friends in my accommodation, who only want a platonic relationship.
From my perspective they just want a male friend right?
When I asked them, what they look in the relationship with them, they answered "just someone who can spoil them, and take care when they can't"
I still don't know what that means.

Not anyone can do that, it has to be the specific guy who they are attracted to only.
I am feeling that is too one sided relationship or friendship from my perspective.
Can someone explain to me why, what and when these kinds of relationships take place.
