I'll say right off the bat that this may seem like an odd place to ask this question, but... y'all are intelligent people, and I'm lost about what to do, but here we go. A 2nd cousin sent me a letter a few weeks ago telling me I have a long-lost brother. Based on the letter's veracity, I had no reason to doubt the claim. I learned it'd been a secret that lots of folks have known, including my aunt, who's like my second mother. Hell, even my maternal grandmother knew about it (who confirmed my mother also knew!). In short, my father had a fling as a teenager, and the girl got pregnant with my half-brother. My father died in August 2021, and my mother in September 2022, so I have few options regarding who to ask. BUT, and this might get confusing, so hang with me, the woman my father got pregnant with was the niece of one of my great-aunts (by marriage... her husband was my dad's dad's brother, aka my father's uncle's wife); weird, but not entirely gross I guess??). The letter provided me with her contact information. I managed to track the guy down on social media using the information in the letter, which also suggested he had tried at least once to reach out to my father. Forgive me if I'm rambling, but what would YOU do? I have no delusions or even intentions of assuming he will magically become my big brother or anything, but I reasoned that if he's tried to reach out before, he has questions about what his dad was like - I know I'd wanna know that, so I've been on the fence about reaching out and extending an invitation.
