Dp and I don't officially live together but he has been staying 5 or 6 nights at mine for a while. I recently had a water bill and I have always paid £35 per month but it had gone up to £66 due to the extra water being used by dp (I checked it wasn't price increase or any other reason). He was there when I opened the bill and I expressed my concern that for year now I am paying double what I was. His reaction was "well I'm not giving you any money towards it, I've got my own bills". Not even oh I'm really sorry that's happened or let's have a think about what we could do. Even a token gesture of £10per month or buying a food shop would have helped but that reaction was so selfish and uncaring. Plus the fact that his bills will go down when he has a review as he's never there! What do you think?
