This is hard

So I come from my long day at work home, and I am tired, but otherwise ok.  Then I saw picture:  my daughter's graduation, last year.  And my heart sank.  I just realized it might had been the last time my daugther had her dad and her mom together in one place at the same time.
I remember it was brief, he left because he had things to do after the graduation. But
there we were, her parents.  Mom and Dad.   I grew up the daughter of a divorce couple, and I have never seen them together in the same room. Ever.  My parents divorce when I was a baby.   
And as sad, and at times bad, my marriage was,  I started crying because in a way I know she won't have us again like that.   It is a big sadness to bring to your children. No matter what age they are. 
As a woman I know I did the right thing.   But as a mom, today I cry for my daughter's heart because I know that we all loose a little hope when our parents loose theirs. 
I hope she will be strong, that one day even she understand me as a woman, and maybe she will forgive me as a mom.
I really hope so...
