No cause to fret

No dear, my space is protected
you can't stepin here,
You speak of my sharing space with another
your not the same, am I clear?
I've learned from that experience, you know,
so, my gates I've shut tight
you're trying to push them open once more
You know that's not right.
With that other I shared a special bond
beyond all bonds you've known
That's over and done with for life
You can't produce a clone.
our shared space has shrunk, you say
perhaps it is indeed so
We'll manage fine I'm confident
So cheer up, shine, and glow.
