Your character changes for various situations anyway, you are a different person with your partner opposed to your friends, you are a different person with your work colleagues, a different person with your parents and a different person with people you've never met. Most people are completely different online compared to offline.

You have to have different versions of yourself in order to suit environments and to achieve various goals. Are all of those fake?

You are always you. You can't fake you, you are just different versions of yourself for various situations.

This being fake thing is often misconceived as some form of lying, but it's really an entirely different thing. Trying to change the way he's always approached attracting others is not lying, it's trying something new.
