Some family arrangements may look unusual from the outside, but that does not mean they are broken. A child can grow up deeply loved and secure even when their story does not fit a traditional pattern. Problems often come from outsiders who insist their version of family is the only one that counts.
The original poster (OP) and his older sister were born through an agreement between their father and his longtime best friend. She helped him become a parent but never took on a maternal role, and the siblings say they had a happy childhood.
Now, the surrogate’s parents have discovered the arrangement and want to enter their lives as grandparents, despite years of absence and several disrespectful comments about their father. Scroll down to find out whether readers believed OP owed them a chance or had every right to keep his distance.
Two siblings reject a relationship with their surrogate’s parents after a hidden family secret emerges
Sharing DNA with someone can create curiosity, but it does not automatically create a relationship. The OP and his sister grew up knowing exactly who their parent was: the father who wanted them, raised them, and built a happy life with them.
Their biological mother entered the arrangement to help her best friend become a dad, not because she wanted a maternal role. Learning that her parents now expect to become grandparents does not obligate the siblings to rewrite that understanding.
The emotional tension comes from conflicting definitions of family. The older couple sees a biological daughter and therefore considers the OP and his sister their grandchildren. Discovering that these young adults existed without their knowledge may have brought grief, shock, and a sense of missing twenty years they can never recover.
However, the siblings do not experience those years as stolen. They remember a loving father and a childhood they would not change. Being told that their upbringing was somehow deficient—especially because their father is aromantic and asexual—turns an invitation to connect into criticism of the family they already cherish.
A fresher perspective is that the grandparents may be seeking validation as much as connection. Accepting the original arrangement would require acknowledging that their daughter intentionally chose not to parent and believed they would disregard those boundaries.
By insisting that biology made her the “real mother,” they can position themselves as excluded victims rather than confront why she kept the pregnancies private. Their reaction may unintentionally confirm her concerns.
The American Society for Reproductive Medicine defines a gamete donor as someone who contributes reproductive material without intending to parent the resulting children.
Its guidance emphasizes informed consent, counseling, and clearly understood roles because third-party reproduction can create competing expectations among biological contributors, intended parents, offspring, and extended relatives.
Family psychologist Nadine Kaslow has also noted that modern family structures extend beyond a traditional two-parent model, including households led by single and LGBTQ+ parents.
Applied here, genetic ancestry is meaningful information, but it is not a command performance. The OP and his sister may someday want medical history, occasional contact, or a closer relationship.
They may also want none of those things. Any connection should develop at their pace, without requiring them to call the woman “Mom,” accept instant grandparents, or defend their father’s ability to raise them.
The most realistic response is a brief, united boundary: they appreciate the couple’s feelings, but they are not seeking a grandparent relationship and will not tolerate criticism of their dad. No debate is necessary.
The grandparents are allowed to feel loss. They are not entitled to cure that loss by assigning roles to adults who never consented to them. Family can begin with biology, but lasting belonging is built through presence, respect, and freely chosen connection.
These are the responses from Reddit users:
These Redditors said OP owes them nothing and can choose who belongs in their life
These commenters advised demanding no contact and pursuing legal action if harassment continues
These users defended the father’s parenting and rejected claims that he gave them a bad childhood
These commenters urged OP to ignore the strangers’ demands and protect their peace
This user questioned whether the surrogacy story and hidden pregnancies were believable
Should the siblings leave one carefully limited channel open in case the grandparents become more respectful? Or did their immediate prejudice prove that blocking them is the best way to protect the family that already exists?
