How can I show I don't need him in my life ?

Some people may know already. I have a ex boyfriend is a captial dick, treats me like crap and I let him. After one post I had, I asked what i should do about him and just about every answer was to kick him to the curb.

I now plan on doing so, but the question is how can I show that I don’t need him in my life ?

guys- what would a girl do to you see they don’t need you ?
