How do you determine if somebody you're dating isn't a date anymore but has become a girl-friend... Are these the correct criteria to check for:

• How long have you been seeing her?
• Phone call frequency - are you on a daily?
• Do you have to ask her out on Saturday night or is a date implied?
• Does she have anything in your medicine cabinet?
• All of the above?

So if somebody you're seeing wants to spend her birthday with you, does this supersede any of the criteria as mentioned above?
