I have a bad relationship with my dad. How do I tell him how I feel?

The family relationships that emerge after divorce or separation affect children as much or more than the divorce itself. In the bitterness and acrimony that so often accompany divorce or separation , it is very difficult for parents not to involve their children in the battle. When children feel torn between parents this usually produce feelings of self-hatred and guilt and may reduce his or her chances for happiness, fulfillment and success.
I can relate to what you have been through I grew up feeling that “all relationships are unreliable, doomed to unravel someday in betrayal and infidelity.” I was afraid to love and be loved, and I kept all relationships on a superficial level. I kept myself extremely busy through out the years striving for success. I cried a lot during those years but was determined not to destroy myself. In relationships I was so desperate to be loved that I gave too much and was treat badly. Your experience is similar to mine, what was worse it was my mother who treated me that way. I started studying the bible and then had a different outlook on life and people's behavior as God sees them. I was separated not only from my mother but my siblings for 35 years. We are now building a relationship and even though the pains come up from time to time, I feel there is healing. Your father may feel ashamed. Try and call him from time to time and talk briefly about something positive. Keep trying little by little build that relationship. Do not throw blame at him. You have to deal with this lovingly. After a while when you feel he is willing to listen invite him out and tell him how much you missed and how you appreciate your relationship with him now. Don't be in a hurry try to build the relationship because you are the one who will benefit more and you will find eventually find healing.
