AITA for telling my son he has to be respectful if he wants to live with us?

A divorced dad welcomes his university-aged son back home rent-free, expecting only basic cleanup and respect toward his live-in girlfriend and her 5-year-old daughter. Months of kitchen messes escalate to profanity and a slammed door when the girlfriend asks the son to clear his dishes. The father lays down the law: respect or leave.

What makes the story more complicated is the son’s overnight exit to a friend’s couch, radio silence, and the dad’s guilt over a tight student-housing market. This domestic detonation tests where parental support ends and adult accountability begins.

‘AITA for telling my son he has to be respectful if he wants to live with us?’

The son returns home for college proximity after years of split custody.

The dad’s girlfriend and young daughter join the household; messes mount.

A chaotic kitchen pushes the girlfriend to tears and the son to profanity.

Adult children testing household rules often reveal deeper tensions in blended families, where unspoken resentments can boil over mundane chores. In this case, the father’s minimal expectations—cleaning up and speaking respectfully—clash with the son’s sense of entitlement after years of pandemic-era leniency at his mother’s house. The girlfriend’s role as a non-parental figure adds friction, especially since she sometimes steps in to clean, potentially undermining the dad’s authority and fueling the son’s rebellion.

Opposing views highlight possible missing context, such as prior conflicts or the son’s adjustment to sharing space with a young stepsibling. Some might argue the dad escalated too quickly by threatening eviction, ignoring the housing crisis for students. Yet the broader social perspective underscores a generational shift: many young adults expect independence without accountability, while parents in remarried homes navigate enforcing boundaries without alienating their kids. This incident reflects wider debates on cohabitation norms in non-traditional families.

As family therapist Dr. Laura Markham notes in her book Peaceful Parent, Happy Kids, “When kids push back against rules, it’s often a bid for connection or control—address the emotion first, then the behavior.” This approach could guide reconciliation, emphasizing empathy alongside firm expectations.

Here’s what people had to say to OP:

Many users rally behind the father, stressing that basic manners justify his firm stance on respect.

A few commenters urge caution, suggesting underlying issues deserve exploration before final judgments.

Others inject humor to lighten the mood, imagining the fallout in everyday family chaos.

The father upholds reasonable house rules for his adult son, leading to a blowup that exposes cracks in their blended living situation. While the son storms out, the dad weighs family loyalty against enforcing respect, leaving the door open for potential reconciliation amid tough student housing realities.
