Guy prioritizes brother's comfort over wife's breastfeeding convenience

A Reddit post from r/AITAH where a man asks if he's wrong for telling his wife to stop sleeping topless while breastfeeding their toddler. His brother is temporarily staying in their room due to a divorce, forcing the brother to enter their bedroom to access the only bathroom, which creates awkward situations when the wife is exposed. The husband dismisses his wife's concerns about the inconvenience of repeatedly dressing/undressing.
