AITAH For Not Supporting Cheating Wife Through Divorce?

A 35-year-old man is divorcing his 34-year-old wife after nine years of marriage, during which she had affairs with women for at least the last three to five years. She now wants to be with one of her partners and has expressed deep remorse, but he feels betrayed not just by the infidelity but by the years she kept it hidden. With a 12-year-old son caught in the middle, the husband wants shared custody yet refuses to give his wife any financial settlement, believing she deserves nothing for wasting his time.

What adds layers to the pain is his resentment over the impact on their child and the appreciation of their home from 800k to 1.3 million, which he bought but now sees as marital property. He’s torn between punishing her through costly legal battles and protecting his son’s well-being.

‘AITAH For Not Supporting Cheating Wife Through Divorce?’

A long marriage ends after the husband learns of his wife’s secret affairs.

This situation captures the raw anger that follows long-term infidelity, especially when one partner concealed their sexuality or preferences for years. The husband’s fury is understandable: discovering that a significant portion of the marriage was built on deception can feel like stolen time. His desire to withhold financial support stems from a need for justice, yet divorce laws in most Western jurisdictions treat assets acquired during marriage as joint, regardless of fault, unless a prenup exists.

Opposing perspectives highlight the child’s needs. While some might argue the cheating spouse should face consequences, many emphasize that punishing the wife financially could indirectly harm the son, reducing her ability to provide a stable home during her custody time. Revenge-driven legal battles often drain both parties and create lasting hostility that affects co-parenting.

Broader societal views on fault versus no-fault divorce show a shift toward equitable division to protect dependents and encourage clean breaks. Here, the husband’s acknowledgment that his wife is an “amazing mother” suggests shared custody is right, but channeling betrayal into financial warfare risks turning him into the source of ongoing family conflict.
