If you dont care, is it because you've lost attraction but still want to be with her and see her more as a friend or you don't love her.

I would care if she did, because girls even with no strings attached, get emotionally connected to the person they are having sex with. Even when they say they aren't... chemically females get attached by sex. Which would take away from the emotional relationship that we share.
(Yes it seems like a double standard, but it has reason)
A guy who has sex with no strings would be seriously having sex with no strings. He could do it and still love and care for his partner, it would be sheer entertainment for him and he wouldn't have any need to put any feelings on the other female.1
