My son is 19, has a well paid job, a car, good friends... in short he's what I would call a functioning young adult. He lives with me (single mum), pays no rent whatsoever and despite constant reminders (daily) never cleans up after himself. He and his girlfriend – who seems to have accidentally moved in –treat it like a student house; rubbish bags littering the landing; washing up piled up overnight in the sink; my daughter's bedroom (she's at uni)/office used as a dumping ground. We have had daily rows for the past year and I am exhausted. I am at the end of my tether and want to ask him to move out.. am I an awful mother for asking that...? Anyone else facing this problem?
