I'm Not, You're Not

I'm not like your last guy.  You're not like my mother.
Those and need are the reasons we lean on each other.
We met.  We were single.  If that's why we're together
When any distance is involved, it strain and tests the tether.

I'm not free this morning.  You can't cancel on friends.
Our streak of meeting daily meets its end.
I go to see the game that night.  You read while I'm away.
It's your friends who go out next time.  We miss another day.

It's gotten so each of us stand on two legs.
You aren't gonna cry, and I'm not gonna beg.
That's why as we grow stronger, we also grow apart.
That's why we'll someday break it off, and it won't break my heart.
