AITA for insisting on a paternity test before accepting my ex-wife’s son as my own?
A 32-year-old man, divorced after discovering his ex-wife Jane’s infidelity with multiple partners, faces a dilemma when she claims her two-year-old son is his and requests financial help, having been abandoned by her recent partner. His mother, eager for grandchildren, pressures him to support the child, but he insists on a paternity test due to Jane’s history of deceit, sparking tension as both women oppose legal processes, citing the child’s resemblance to him.
The conflict escalated when his mother posted a Facebook photo calling the child her grandson, prompting family and friends to label him selfish for demanding proof before accepting responsibility. Is he wrong to prioritize a paternity test, or are Jane and his mother unfairly manipulating him into accepting an uncertain obligation?

Jane and his mother oppose legal involvement, citing physical resemblance:






The man’s insistence on a paternity test reflects a trust violation (Gottman, 1999) stemming from Jane’s infidelity, which shattered his ability to accept her claims without evidence, a reasonable stance given her history of deceit. His mother’s pressure, driven by her desire for grandchildren, introduces family pressure (Bowen, 1978), creating an emotional burden that overlooks his need for certainty and risks manipulating him into an unverified obligation.
Jane’s opposition to legal processes and reliance on superficial traits like eye color suggest possible ulterior motives, potentially using the child to secure financial support, while his mother’s public Facebook post amplifies the family pressure by rallying external judgment. This dynamic places him in a defensive position, as he balances personal responsibility with skepticism born from past betrayal.
The situation risks long-term relational strain, as his refusal may alienate family members who prioritize emotional bonds over evidence, while accepting the child without proof could lead to resentment if paternity is disproven. The public nature of the conflict, via social media, further complicates his ability to navigate this privately.
To move forward, he should firmly pursue a paternity test, ideally through a neutral third party to minimize conflict, and consult a lawyer to understand potential legal implications, especially in their jurisdiction. A mediated conversation with his mother could clarify his stance without dismissing her emotions, and therapy may help him process the trust violation and external pressures, ensuring decisions align with his values and clarity.
