I am sorry for your loss.How did it happen,was it a sudden thing,an accident or had he been ill and his passing expected?Grief can mean you hang on to his things longer or it can mean you want to let go,the choice is yours.There is no right time to sort through belongings,it is up to you,if you feel ready and it feels right then it's not too soon.It must have been difficult to be in your home surrounded by his clothes and stuff when you have lost him.I understand wanting to sort things so do what feels right.Once again I am deeply sorry for your loss,honour your grief and give yourself what you need to get over your grief and move on.
