my children are alot younger than 18 and am struggling to advise a friend who has an 18 ds who has got into debt with wonga and mobile phone and who thinks by ignoring them they will go away!!! she has experienced debt with ex husband and is worried that as her ds is registered at her address she will be black listed when has only just got a good credit rating, he is also dabbling in weed and using money for that. should she pay his debt off and then ask him to leave? (confused)
