Hi, My dad committed suicide when I was 13 and a year ago was the 20th anniversary of that day and I planted a tree in our yard and my husband had gone to a pottery store where you can paint and bake your own pottery piece and he made a special stone (like a stepping stone only for show not stepping) and it was so special and we have the stone in front of the tree to serve as a monument to my dad (he and I were VERY close and his suicide was a shock to the entire family). I have since built a brick flower bed around it and plant and garden in that space.
I would be a great idea to buy a tree for the wife and make or buy a special object to place in front of the tree (this way she can take this object if she ever moves and it can be passed down to other family members later)
Have a prayer and rememberance seremony voicing your thanks for his life and the gift of friendship you had with him and the gift of love and friendship you now carry on with his wife. also promising to always be there for her in friendship to look after her for him....
I will add that after my Dad died- (he was a prominate leader in our community and had many "friends")
people sor of just forgot about us and we never saw many of the people who we condidered our best friends for years... I guess they did not know what to say or it was to hard for them but it is harder on the person who lives it every day and when "friends" walk away it is even harder to walk yourself through each day.
I am sorry that you are going through this and I wish you well
Hope that helped,
A. J
