Sometimes there is nothing more that I can do, except stop hurting myself or other people.
I tried for one and a half decades to save my marriage. I did not know about addiction then. When I did, I had to divorce him for my own safety and sanity. He was so hurt. He thought I was "bored". He never saw the wreckage.
When I made amends to my best friend, she said she never wanted to see or speak to me again. She never has.
I once brought a speaker to my AA club. He was the most phenomenal AA I'd ever met. After he spoke people flocked to him to ask him questions. One man asked, "How do I get my wife and children back?" He said, "You may never get them back. But what you can do is be the kind of person whom they would be happy to be with, should they come back."
Yes, that's something I can do, with God's help.
But, being an alcoholic, I can also be of service to those who are still suffering. This kind of balances the books for me.
And I can enjoy the life that I have been given, in gratitude to the One Who has given it.
My prayers are with you, friend.
