To give a vague counterpoint. I have 3 full siblings, and I also have 3 half siblings who are all over a decade older than me. My half sister I see at xmas every other year (when I am in the UK), we don't communicate outside these points but get along well enough.
My oldest half brother I see on a similar frequency but chat a little on whatsapp in between. He is a bit of a second dad for me after our own dad died a couple of years ago. I love him to bits. My other half brother I ADORE him. I see him twice a year, sometimes three times a year and we chat ALL the time.
He'd go far out of his way to help me and I'd do the same. I love his wife, I'm close with his daughters (who are only a year or two younger than me). My kids adore his granddaughters, it's wonderful. I wouldn't be without him.
What a wonderful, lovely, fluffy, sugary, gooey story. 🙄
However, it seems from your tale of joy and elation, that you have known these half siblings for many years...... (since you were quite young by the sound of it,) and they have been a part of your life. And also that the father you all lost was very dear to you all.
Not quite the same as a half-sibling popping up in your life, when you're in your 30s or 40s (or older,) who you have NEVER met before, and who has the same father, who you went no-contact with several decades ago, because the relationship was toxic, and damaging to your mental health and well-being.
Not quite the same, IS it?
