i'm not good at sharing

i figured it out.
why i have these walls.
the ones that always tear you and i apart.
i build myself up to this great, giant thing.
and i find you, this other great, giant thing.
and of course we stick to each other, because we're both amazing awesome things.
and as time takes it's course, we begin to bond, and we both become dependent on eachother.
because you see, we're both bonding our awesomeness. 
but then i realize that we're morphing into each other, like normal people do.
and i panic. because i don't want to lose this great, giant thing i've built myself up to be. 
but today i realized that all that time i wasn't loosing anything, i was gaining everything.
instead of sharing, it was more like trading.
upgrading, you could say.
we were a lighter and a fuse.
but instead of being a melting candle we were like a raging bonfire.
that makes sense doesn't it?
