don't even think about it

First, even if you withdraw I-485, there is no use, since immigration intention is based on I-140.

Second, once the person has filed I-140, or another person filed I-140 for this person, there is immigration intention, Even they withdraw the application later, there is no use. Immigration intention is already there.

That's why I didn't file I-140 for myself. I know one day I am going to a school to pursue a career that I really love, I don't want to file any risky I140.
