AITA for yelling at my dad and calling him disgusting for what he said to my wife?

A 29-year-old guy completely lost it and yelled at his own dad right in the middle of his wife’s baby shower. The reason? His father had just announced he was marrying his daughter-in-law’s mom, then cracked a sick joke about wishing he’d met his son’s wife first and having to “downgrade” to an “older model.”

Both husband and wife are Korean-American, bonded early by losing their mothers young and sharing similar cultural struggles. Their families had always been close, but the secret year-long relationship between the two widowed parents blindsided them. He wants his dad happy, yet the idea of him dating his mother-in-law felt wrong—and that final comment pushed him over the edge.

‘AITA for yelling at my dad and calling him disgusting for what he said to my wife?’

It all started with the couple’s long relationship and shared background:

Then came the shocking news about their parents:

The breaking point hit at Jenny’s baby shower when they announced the marriage and the dad made unacceptable jokes:

This situation goes beyond a bad joke—it exposes deeper issues with family boundaries and respect. When a father openly compares his future partner to his daughter-in-law in a sexualized way, he’s seriously disrespecting his son, his son’s wife, and his own fiancée all at once. It shows an alarming lack of sensitivity, especially in cultures that value discretion and family hierarchy.

Clinical psychologist Dr. John Grohol, founder of Psych Central, has noted: “Sexualizing a family member, even in jest, can cause lasting damage to relationships and individual self-esteem” (source: Psych Central article on family dynamics and inappropriate humor). The dad’s remark didn’t just demean Jenny’s mom; it implied sexual interest in his daughter-in-law, which is deeply inappropriate and could border on emotional harassment within the family.

From the son’s side, exploding in anger makes total sense. He was protecting his pregnant wife and their unborn child from toxic words on what should have been a joyful day. That said, going no-contact might escalate things further. A practical step is to wait for emotions to cool, then have a private father-son talk to express feelings clearly. If the dad won’t acknowledge the harm, some distance could be the healthiest choice for now.

Finally, Jenny’s mom needs to recognize this red flag too. Hearing her partner publicly regret not pursuing her own daughter is troubling. Ignoring it risks long-term toxicity for the extended family.

Here’s what people had to say to OP:

Pretty much everyone sided with the son, calling the dad’s behavior outright disgusting and unforgivable:

A few acknowledged the step-sibling joke as somewhat common but still ruled the “older model” line way over the mark:

Many suspected the dad’s real motives, suggesting he was attracted to the wife all along:

Others pointed out additional issues like timing and family reactions:

This whole mess leaves a bad taste, showing how one crude comment can shatter family trust in seconds. The parents may have every right to find love again, but the way they revealed it—and the words chosen—made their kids feel betrayed and deeply hurt.

In the end, the online community overwhelmingly backed the son’s outburst. What would you do in his shoes? Could you ever forgive something like that, or would permanent distance be the only option? Drop your thoughts in the comments.
