Women use their male friend group as a Swiss army knife. They have some guys for sex, some to be an emotional tampon, others that will get them into places by paying for them or being able to hook them up with limited tickets, others to do general labor for them, and so on. Women only see men as tools, and they want these men in their lives to slave for them. The only one that's getting a good deal is the one they fuck. Everyone else she purposefully manipulates with the possibility of a deeper relationship even though she claims she isn't doing it because she knows she has to manipulate these men so they don't use that energy in trying to woo another woman.
