Sense: phrasal verb/2
'Wallow in' is more critical than 'dwell on' or 'brood over' because it suggests someone is almost feeding the feeling. 'Dwell on' can be neutral or mildly negative, while 'brood over' focuses on silent unhappy thinking. 'Move on' is the opposite: it means leaving the bad feeling or event behind.
