Fathers of disfigured

I must be the only person feeling this right now, besides the person who I didn't think would feel it.

my brother has left his fiance.
Who even knows why. His reasons seemed to be simple frustration. nothing more.
And more is what we need.
What a fool he is.
Does he now care how Ava will feel while she grows up? Does he not care that she woke up in the night saying "daddy? Daddy?" and could not find him?
Does he not feel PAIN? Does he not fear that Halesha will move away, and he will not see his little girl frow up?
Why is this normal? Why is it okay to bring a child into the world, and deprive them of the "family"? Why is this normal... It isn't.
He must have felt nothing at my parents divorce. Nothing but gain. neutraility. I just don't understand...
and my mother... good god. I tell her what happened with them, and she moves on to her home business. she has better things to worry about, like spending her time on fixing faces with creams and potions...
I don't understand this. Why is this passing so easily? like its all normal, all in a days work...

My brother is a fool.
Nothing but pain will follow this. Nothing.
And no one will pay the attention needed. No one nurture what needs to grow. No one will hear Ava crying, except for the mother who was left behind, alone with her.
How could he just leave? How could he be silent for so long, and scream about no one hearing him? How could he just go?

Why can't this be fixed?
