This happened to me and I can only give you my perspective.
Growing up I always felt like the black sheep and like I never fitted but I thought it was in my head.
Who I thought was my Dad died 20 years ago when I was 33.
Within a few months my Mum got back with a childhood friend his wife had also passed the same year.
My Mum wanted my to have a friendship with this Man and whenever I would call her she would want me to talk with him to discuss our day.I always thought this was because he had a son but they weren't very close.
Two friends mentioned they thought I looked like him and I even mentioned it to him and my Mum but my Mum told me I was being silly.My Mum had a very strong personality and was quite controlling within my life even when I left home and had my own children.
My Mums friend and herself were diagnosed with terminal illnesses and they were together for around 13 years when my Mum passed.
After I kept intouch because I felt my Mum would have wanted this and I also wanted him to remain in my life.
He eventually went into hospital and then a nursing home.I started visiting 4 times a week and we chatted.He once asked me did I ever have girly chats with my Mum my response was "did he know my Mum" we never had chats about anything and I would say she was a cold person,no hugs no I love you etc.
When he became more poorly I had a awful feeling I just needed a answer to.
So I asked him "was he my Dad" to which he replied "yes" and yet I still didn’t believe it.So I did a dna test and of course it came back 99.9 %
It's crazy that it was something I needed to know but that day it ripped my world apart.
Two weeks later he passed away and in the time before he wasn’t really up for speaking.
I was with him when he passed and went in the family car at the funeral.
A couple of months later I told his sister who thought things now slotted into place.She welcomed me with open arms and we are still in touch.
It turned out my Mums sisters knew but didn't think it was their place to say and they said my eldest sister knew which is something she denies.
He has now been passed 7 years and in those 7 years I had a breakdown,lost my job of 23 years was under a physiatrist,on high doses of medications and suicidal.
If I could change things I would still want to know but earlier so I could have chosen my own path but definitely after the man I thought was my Dad had passes away.I take it he knew and he also knew who the man was.
Even now I break down and cry,I no longer know who I am my older siblings have each other but I feel I am the odd one,even writing this as brought me to tears I'm not sure the pain will ever end 💔
