I think a part of it is about denial, like the constant repetition of 'you're not big in my life'. They're trying to tell themselves that this person they used to love (who hurt them) isn't a big part of their life, that they didn't really love them fully, that they've gotten over them.
"I can cut my heart out just like you do
And I can suck the life out of it just like you do"
This person who has been hurt is capable of doing the same thing -- they're not weak.
"I'm gonna pick myself up and pull myself together; never revel in recovery mode"
They're telling themselves they can get over it, that that person wasn't a big deal to them.
