A friend 'moved in' to our spare room a while back, as he had lost his job in london and had been sharing a room and had enough. We said he could stay here temporarily while he looked for work and a place.
Since then DH has got stuck abroad in his home country (long story involving passport renewal) and the lodger is still here. Don't get me wrong, he has been a massive help with DH away, he's very clean and tidy, does the washing up, cooks for me, has helped with childcare. A treasure. However he's now working casual shifts and isn't here much, so less helping out. So AIBU to ask him to contribute a bit of rent? I'm thinking £50 a week when he's able. I don't want him to move out as he's really very nice and helpful, but he uses water and electric and I also planned to use the spare room for foreign students, which would have been an income.
