Just when everything was too calm for my mind some things suddenly collapse.

Back when I was younger I fell in love with a boy who later was my sisters boyfriend.
I suffered a lot and yet I was happy in the end because it calmed my sister who was always my biggest enemy.
The two of them seemed happy and so was I.
And now the most unexpected thing has occured.
He broke up with her.
When they just found the right place to live.
When they just finally settled down.
After years of being together.

No, really, I know about the fragility of human relationships but for them I really am surprised.
She's gonna come home to us soon and for how long I don't know she's gonna stay here again.
Will I survive?
I love her very much. I do.
But she's hard to handle.
I want her back and I want her to be happy again.
But I don't know if I'm gonna survive this to be honest.
