I would just like to share my story it may help with your decision. My parents separated when I was 2 years old I'm now 60+. I have no memory of my Father and only one photo which is tiny and hard to see I know from my Mum basic information about him, his siblings and parents who are now all dead but I have not idea what they looked like. In the 1990's whilst visiting my Mum, I don't live local to her, I saw a name the same as my Father's brother on a business sign I asked Mum if this was his brother and she confirmed it was. On my way home I took note of the phone number and after much indecision of several weeks/months I made contact with him and explained who I was. He was fine and gave me details of my Father where he was living and how many children he had, he also said he would pass on my phone number to him which he did. My Father did contact me twice and we chatted a little however he made a couple of comments which I was not happy about regarding my Mum and Grandmother which made me a bit unhappy with him but I didn't challenge him. He asked a few questions about my life and knew my Mum had remarried someone in the RAF so as children we'd moved around quite a bit. On the last occasion he phoned he introduced himself as my Father and again made a few unnecessary comments, after this I decided to leave things alone for a while, especially as when I told my Mum about his comments, which weren't really all that bad, just not necessary, it upset her a little, and although she didn't say don't contact him or anything like that I didn't want to open up old sores. Shortly afterwards we changed phone providers and my number changed and somehow I lost his number. A couple of weeks ago whilst updating my research I came across information on a burial site suggesting someone with the same name had died in 2015. Last week I received the death certificate which confirmed it was him and now I feel .... well in truth I don't quite know how I feel totally, there is a sense of loss, and I do know I have regrets especially in respect of having relatives and half siblings that I'll probably never meet this fills me with sadness, life is short and sometimes we need to be selfish towards ourselves, and do what is right by ourselves. Like many of the other's who have offered opinions do what is right for you don't like me have regrets that now I can't put right. Good luck.
