Want to make friends with girl who already has a boyfriend
A few months ago, I met this girl with whom I shared several classes, and we would often talk before and after class and even got together to study once. Now that the semester is over, we no longer have any classes with each other but I would like to still be able to see her, as she is the first (and thus far, only) friend I've made in University. However, because she has a boyfriend (who lives far, far away), I am afraid to ask her for her phone number so we can keep in contact, lest she get the wrong idea. Keep in mind, I have no ulterior motives here, I desire only friendship from her, and my heart already belongs to another girl.
Anyway, is it normal to hang out with a girl who already has a boyfriend if you are a guy? And should I try to keep in contact with her, or not?
