<p>It is very kind of you to continue a relationship with your uncle. Leave it at that. He knows how to contact his children. Your cousins know how to contact their father. It is not up to you to decide when, if, how, or to facilitate this happening in any way, especially given the fact that you have no earthly idea why they are estranged in the first place. Ask and you’ll never get and honest answer from any of them. It’s bothering you, but the relationship doesn’t include you. If anyone in the relationship is bothered enough by the lack of contact they will do something about it.</p>
<p>Several years into my marriage my SIL decided it was a good idea to contact my father and explain to him his absence in my life was inexcusable. That her father, my FIL, had stepped in to fill his role. I did not know of this letter for many, many years. What I did know is a very distinct time when I could pinpoint it’s arrival. My father must have been devastated, but felt so rejected, drew away from me, his grandchildren, and his son-in-law. I had to work even harder to have a relationship with a father that had left when I was 14. Great job sis, way to go!! Thanks so much for your well intentioned intervention. Sometimes these things can backfire and hurt the very ones you think you are trying to help. Unless there is abuse it is almost always best to mind your own business.</p>
