It depends on the woman. Competitive and shallow women prefer to "outshine" their friends in some way, shape, or form. That includes finding friends that are less attractive, heavier, or less accomplished in order to draw men to you vs. the friend in social settings and situations. Many women are competitive and even mask this by pretending to have the best intent in their friendships. Some women still befriend other women based on looks for the "perks" that it can generate at times.....v.i.p., drinks, or other freebies.
I find some women choose their friends based on common interests and character. This appears to be the minoritiy as we get older according to my experiences.
I myself care about loyalty and character when determining the values of my friendships.
