You grieve the death of your spouse no matter the degree of love, or the length of the marriage. The person you were married to is now gone from this earth. Other than the obvious matters of organ donation or not, and all the funeral arrangements there are many other decisions that crop up during the time of grief. The general advise given to many grieving widows is to try not to make decisions that are important and irrevocable for at least 6 months to a year following the death. Many of the material things you shared are connected to decisions.
