Mature cousin met man online, moved him in to Aunt's house few months later. He is unemployed and does nothing around house. Family concerned as Aunty (widow) is unhappy, she pays for everything and does lion's share of cooking, cleaning, laundry. Cousin works but has never been asked to contribute to household costs (Aunty not poor and cousin works in low pay job). Searched man's name on Internet and found out about his past. Cousin did know so not hoodwinked but refuses to tell Aunt. Have agreed to say nothing as cousin says man depressed and suicidal in past. Given my Aunt is anxious knowing nothing about this man in her house is this the right thing to have done?
