I will say it again.
All of the things you have said. Are fine and dandy but.
They have nothing to do with why girls in collage have boyfriends
I was a college girl. I know a lot of former, recent and current college girls. I know very well why college girls have boyfriends
The smart ones defer whatever the reason is or they keep it casual. A guy will be as impatient and ungentlemanly as a girl will allow. Any serious guy will return
Meanwhile, any smart girl will get her education done. Period. Summers too. Then get her career in order
That cannot be done efficiently when she’s involved in emotional entanglements, staring at her phone for a proper response etc
I’ve seen girls (and boys) fail to keep full ride scholarships talking regularly for hours with boyfriends. I’ve seen girls get 3 majors and a couple of masters’ done then working a good job by mid 20s. Can’t be done with a needy boyfriend hanging around
