Good points made. In most cases where separations are difficult, one parent usually tries to hurt the other parent. Unfortunately not often enough do they realize that when doing so, they are not hurting the other parent as much as they are hurting their own child/children.
It’s tough to watch parents do this to their own kid(s), solely because of their anger or resentment toward the other parent. Regardless of how you feel towards the other parent, it is imperative that you put that aside and do what is best for your kid(s). Everyone strives to be a great parent, I guarantee you it doesn’t make you a great parent by keeping your child/children away from a parent who is wanting to be, and putting the effort into being, there for their child/children.
