What's a word for friends that aren't friends?

Because we might start to care about each other.
We might kiss
And we might hold each other until everything falls back into place.
We might never say,
Keeping hands in the openness.

And we may cry when one or the other leaves
From a worn out heart
Or something breath taking that came along.
While we held our spot,
(Baby we weren't ever really dating)
While we grew on each other,
( We never said those exact commitments)
While we slowly became part of the others life,
( I'm sorry, I didn't intend to confuse you)
Because we were too afraid to call it
Something, anything, other.

I will sit in my room
And loop the paradox of friends
(Friends don't kiss each other on the mouth.
Friends don't hold each other naked,
Tight as matching spoons.)

Wearing a disguise will not fool tenderness,
Will not cause pain to pass over you.

This can still break your heart.
