I sit in math class
thinking why y=mx+b
I start thinking about life
and how I could put it into this problem
y would be you
mx would be your and my ex
and the +b would stand for me

y stands for you because
when I decided to take you on
I knew it was gonna be me plus our ex
and I thought it could work

mx is our ex's because they both
just team up together to try to ruin
the happiness we built and so they
are multiplied together because they're
a team.

the +b has to stand for me because
I'm in this situation too and I stand alone in it. He wants me but he could go back to his ex.

I'm so confused why he can't just cancel out the mx and just keep b.
Is just the 1 of me not good enough for all of him?
