Expected but surprising in a bad way

I have known it for soo long
And now my suspiscions have been proven right
I know he's been going out with her..
His phone is filled with her pictures..

At first I don't believe this
Until I've seen it with my own eyes..
I read his messages and I checked his phone
Its filled with her calls and sms'es

But no matter how I want to hate & kill him
No matter how hard I beg to differ
I can do nothing...
For he is my father...
