Peppah, how do you know for sure who is telling the truth? Your dad or your mum?
My ex has been an awful father. I don't give a rats about our relationship, I'm so glad we never stayed together, because my life is far better then it ever would have been with him in it.
It is very hard not to hold a grudge against someone who hurts your child, and would leave them go without though. My ex would say he was comming for visitiation and not show up, he asked my DD to be flower girl when he got married and then changed his mind. He never pays child support, and when I was single and poor I really reall needed that money for her. it would in fact take me days to write all of the awful things he has done to let her down.
I don't dis my ex to my DD, she has figured it out all on her own now that she is older and can see him for what he is, but how can I possibly like a man who would treat his own child so poorly?
Moreover in most cases when men are not in their childrens lives, it is their choice. So it can be hard for a mum to remain neutral when she sees the hurt a father can cause, when he is supposed to be loving and protecting his children.
