How do you differentiate between your female friend and girlfriend (Apart from physical affection)?

Are there things that you keep for your girlfriend/partner only and never do it with with your female friends? For example, would you give your female friends this much of freedom to open your wallet or bag in your absence? Would you ask your female friends to hold your personal things like your phone, keys, headphones, handsfree, ID card, etc? Would you do favors of standing in the line of two hours to get a chore done for your female friend? Would you pay for food for your female friend? Would you ask your female friend to let you drop her home on a bike?

What are the things you would only do for your partner or girlfriend and not for a female friend? How do you differentiate? What things do you keep or do specifically for your special one only?
