I will not love you until the end of time, 
because I can't. 

None of us will see the end of time, 
the end of the universe as we know it. 

we will never see when the stars go dark 
because of the expansion and we can
no longer see the galaxies that were once so close. 

we will never see future civilizations rise and fall, 
a clash of wars across a desolate Earth. 

we will never see when the human race dies and there is simply 
a lonely planet with the remains of computers that long fizzled out. 

Maybe there will nothing there to realize that 
it is the end, and the entire world simply goes 
in a quiet sort of peace. 

We will never see anything past our maybe 80 years of lifespan, 
so I will not love you until the end of the universe because I can't. 

And maybe I won't even love you the rest of my life 
because how do we know that we are perfect for each other 
when there are so many things that I don't even know about 
myself yet.

But I will love you when I do and that should be the most important thing
because another human being looked at you and said that you were the one 
and then maybe it didn't work out, and maybe she cheated, 
and maybe you decided you were better off as friends, 
but for that brief moment, 
you were in love and happy, and that's all that matters. 

I won't love you to the end of the universe. 
I might love you until I die, 
and then if there is an afterlife I might love you then too 
but I promise
no matter happens
that I will love you when I will love you 
and 
we 
will 
laugh 
and 
light
and 
eat
and 
breathe
together. 

And it will be amazing, 
and that should be enough for both of us, 
even if we go apart in the future,

I will love you when I do, 
and nothing more than that.
