How do I stop my friends for being close to me just because of my brains?

How do I stop my friends for being close to me just because of my brains?

Only one seems real. The rest only contact me when they need my editing abilities on their write up or graphic design or to play guitar or sing at their parties to entertain their guests.

Today one contacted me to make a CV for her and I started feeling used for the first time even though this is what my fiance has been telling me. I'm yet to respond to her SMS cause I'm upset.

Do I start charging them?
