My MIL died suddenly 8 weeks ago. It has been left to DP and I to sort out her things and clear her house to either sell or rent. We have been to the house several times to try to sort things but DP finds it difficult and is upset for days after. He has brought boxes of things back to our house but cannot let go of them ie. take to charity shop etc. We have the plastic hospital property bag containing nightie, slippers etc which I can't get rid of for fear of upsetting him but then he can't throw away because he can't bear to think about it. Any advice on the best way to help DP?
