I don't understand modern dating etiquette. My niece told me yesterday that she and her bf are now 'officially' boyfriend and girlfriend . I don't understand it as they have been dating for a year. He just assumed they were but she told him he had to ask her to be his gf. I just don't get it.
Apparently it is also necessary to agree to be exclusive.
In my day you 'went out' with one person and if you met someone you preferred you 'finished' the first relationship; 'two timing' was really frowned upon.
When did it all change and why?
