I have received a letter from Concentrix asking me about living with someone. I am really stressed about this letter. I bought a house with a friend who lives in the house too. We live completely independently in the same house. I am a single person and look after myself and my two teenage sons, both of whom have autism. I pay all the bill, i.e. Gas, electricity, council tax, etc and my friend pays me a contribution for his share. I work 30 hours a week and my boys get DLA. I have my own bank account and can send all details of this to them. I do not socialise, go on holidays or cook etc for my friend. He looks after himself and does his own thing. I am really concerned of how I can prove we are not in a relationship because we both live in the same house. I work so hard with my boys I have no interest in a relationship whatsoever. I am so stressed about this. I rang Concentrix this morning and am going to forward the documents they ask for but am still feeling I have to prove my position. Please give me advice
