You shold go if you really "need" to for closure. Personally, I feel that if you and your father had a good relationship, and you both have shown "love" for one another, that in itself is "closure."
I know from what I speak....My mother recently has died in a nursing home. After being "earased" from the family years ago by my sister. (A long story, too long to tell.) My sister had "controll" of my mother and even though my mother welcomed contact, she was "influeced" not to.
Making a long story short....when I found out where my sister "put" my mother, I started to visit her....it was "so beautiful" having a mother again....Not having the influence of my sister, Mom "welcomed" me and I asked her forgiveness. She forgave me, we hugged and kissed....Then I visited her about 3 more times befor she passed away.
The fourth time I was to visit her with my son, who came especially to visit mom. He cam on a flight from another state.
When he called the nursing home to find out if Mom was feeling well enough for visitors, the nursing station kept forwarding his call to other stations...........I will never forget my son's expression when he was told that my mother "passed away" three days earlier. (My dear sister never called me to tell me this.)
I knew as soon as I saw his face...and cried along with my son, in disbelief that my sister could be so "cold." She knew I was visiting my Mom and didn't even let "me" know that she was dieing.
She still hasn't called me, even after my son left a "loving" message on her message machine...(She never answers the phone.)
Now don't get the idea that we left a cruel message, my son is a minister, and only believes in forgiveness and loving another person that hurts you.
I found out that my mother was already creamated when I recalled the funerall home that was used for my father. (She did the same to me then, but had a death notice in the paper saying that "services were held with "imediate family", which I was not included.
I have put it all in perspective. My sister would have made a scene anyways, and me, having parkinson's and recently a cancer operation, did "not" need to go through all of that.
I feel that my mother told me she forgave me, and I forgave her. We enjoyed our "very short relationship" of mother-daughter again...But most importantly,I know that my mother Loved me and my children very much......and "that's what really counts." It has brought "closure" and I thank God for making that happen.
