Totally unacceptable behaviour, and the rest of the flight doesn't sound much fun either.

However if your husband was also on the same PNR then you aren't making best use of Theoretical Seating - the system has some code in it that doesn't like window + aisle combinations, where the middle is left empty. Your better bet is to book yourself the two seats together you can best live with, leave either the aisle or window empty, which ever you don't mind losing (windows are more sought after than aisles) and then put the highest status passenger in the middle seat. However if the flight is full, the flight is full.
