I don't think anyone can tell you exactly what it means without knowing more details about your relationship and your bf's personality. From what you wrote, it sounds like he is being very honest with you. That is much more info than most guys would share with their gf's if another girl showed interest in them. Also, the info he shared with you is normal info that you might find out when meeting a person for the first time. Regardless of her feelings toward your bf. Would you rather he kept the info from you and interacted with her behind your back? Perhaps he only wants to be honest with you so that you will feel you can trust him and won't worry what he is doing when you aren't around. I wouldn't over analyze this or worry too much unless you have a reason to suspect your bf is being unfaithful.
