It's really sad to hear such story and I will like to express my condolences.
Both of you have great memories with each other and the memories will stay with both of you even when you leave this mortal world.
The memories will be there and stay on forever.
The pain will still be there deep down and there is nothing you can do about it.
Just accept the fact and live on with both of your memories.
She will be happy and feel comforted.
