Sorry for long post. My two sisters and I (all in our sixties) have known for about 20 years that our dear mum, who died last year and to whom we were all very close, gave birth to a baby boy when unmarried in her late teens. He was subsequently adopted.
I never spoke to Mum about it, but my two sisters did, albeit briefly as Mum apparently was adamant she didn't want to pursue the topic. She never made any attempt to contact him, and he didn't attempt to contact her or any other family member during her lifetime. When Mum died, he did make contact (aged 68 at this point) via my younger sister. According to my sister's reports from her subsequent conversations/meetings with him, he had a very happy upbringing with his adoptive parents, has had a successful career from which he recently retired and has been in a stable relationship for many years.
So that's the background - the thing that is now making me very uncomfortable is that my sister and my niece who are both very enthusiastic about embracing him into the wider family fold (my other sister currently want nothing to do with him), are pressuring me to strike up a close relationship with him. "It's what Mum would have wanted" "You'd really like him" "We owe it to her" "He really wants to get to know his genetic half-siblings and their families" etc. I've got nothing against the guy, I've spoken to him on phone, we've exchanged polite emails, I've sent him some photos of Mum when she was younger as I thought he'd like to see them, and I'm happy enough to bump into him at some event like a wedding in the future should my sister or niece want to invite him..... but I feel no automatic connection to this person just because he is genetically related to me and have no desire for him to become a regular part of my life. I've made it clear to him that I bear him no ill-will, which I absolutely don't, but he and my sister and my niece keep trying to persuade me to meet up with him. I don't know at what point I become insistent and tell them to butt out? I just feel I'm being pressured into it. I'm not ruling out a future meeting, but if that's what I decide, I'd like the invitation to come from me on my own terms. I feel I've stated my case to those involved gently and without being unfriendly or judgemental in any way. Am I being totally unreasonable or do I just need to lay down the law and tell them stop hassling me??
