My guess was she was going after guys that are going after multiple girls. Women are attracted to those types naturally. Then they feel like they weren't enough when those dudes inevitably start chasing after some new girl. It's the cause of depression in most women I meet with severe depression.

I never get as many girls after me as when other girls are after me.

It affects guys the opposite way. Guys with fewer options in girls get hung up on one girl so easily. Causing severe depression if she goes with someone else.

Too bad about this girl though.
