Not invited to funeral

Well it’s not a slight on you as it’s only 8 close family so I think you must accept the thoughts behind it , even if not agreeing or understanding. I d buy a bottle of your favourite tipple or cup of tea if you prefer and quietly celebrate his life and your friendship, your way in your heart and in your head, at the time of the funeral
Funerals are just outward showing of grief and very overrated in my opinion
When my close friend died I didn’t want to go to her funeral, all her friends were dressing up and having a party, and that was their way, for me I spent my time alone just think about her We re all different
Don’t be sad for the funeral, be sad for your friendship leaving you and for his suffering, but don’t be sad about the outward stuff . Do it your way

My mum made her wishes clear. She didnt want a funeral with lots of people. She only wanted 'the breakfast club' ie immediate family who went out with her every month. We adhered to those wishes. A funeral is hard to organise and please everyone so just think of your friend and drink a toast to him.

My younger, twin brothers died a few months apart, four years ago.
The first brother to die wanted no one in attendance for his cremation.
My sister in law rang me to explain, thinking that I might be upset at not being able to attend. I reassured her that I was perfectly happy with my brother's wishes and I would quietly think of him on the day of his cremation. He was not religious.
When my second brother died his wife also contacted me to say that the only people present at his service would be the priest and herself. My brother and his wife were practicing Catholics and the priest had been very supportive throughout his illness. I sat in a Catholic church in Oxford, quietly remembering my brother at the time of his short service prior to cremation.
I feel I have said goodbye to my brothers' and have respected their wishes. My acceptance made it easier for their widows. I have no regrets regarding the way things were done.
I send you my kindest condolences for the loss of your dear friend. May you too find acceptance and peace.
