Should i cont to color my hair since my husband ped i have not cared to is this wrong?

It is not wrong to decide not to color your hair. But if you have not done so because you have given up on your appearance then I think it is self destructive. Sometimes the outside helps the inside. So, do your hair, and your nails, put on some make up and wear a clean outfit. Remember the good times that you had with your husband. Keep up your appearances it will make you feel better, and remember that grief is a personal thing, you don't need the approval of anyone to miss your husband.
