I agree. Just not always. All it takes for a guy and a girl to be friends is for them to not be attracted to each other. If they are in a relationship with someone else, it is also paramount for them to not cross relationship boundaries (even if they aren't attracted to each other).
Absolutely, I can try at least - I've written checklists and guideline lists on several threads by now :-).Now you can warn/educate others about abt boundary crosses and any disrespectful fratinizing when one's friend is in a romantic relationship with another.
