I + U = We - U = Me

This is a complex problem
yet so seemingly simple to solve
I'm not a great mathematician
but is it really so hard?
I know I shouldn't add you 
but why don't I want to subtract you from my life
Instead I keep mulitplying, dividing
over and over again
My cerebellum begs me to stop
Complete frustration is what I feel
as I spend countless hours
with pencil and paper
attempting to figure it out somehow
And when my teacher tells me how I can find a solution
I keep insisting there must be a way in which 
I could use both addition and subtraction
and get the answer on my own
But wait- who's the teacher again?
If this were plane geometry 
we could never be congruent
You don't equal me
I don't equal you
We don't equal each other
Yet some say to move the decimal to the left
and it will be even
But it's still not adding up right
cause that would bring me back to division again
Since I'm a prime number
I'm indivisible
Unless you were the same number but
your not
I am a positive integer
You're a negative
If we were added together
I would become negative
and that clearly is not the answer I'm looking for
Why then does this equation seem to be so complicated?
When it's so easy to see that we're
mixed numbers
improper fractions
Deep down I know what the answer is
but I'm still trying to convince myself there's another way for it to be right
So I sit-
Contemplating,wasting time
as day turns to night
night to day
with pencil and paper in hand
When all I have to do is 
Subtract and Erase
