As I am working my way through this with my AW, separated 9 months now, I have discovered the opposite of love is not hate, it is indifference.
Also, love is not permanent. It is OK for it to end. Sometimes it's just time to move on.
BTW, I do believe I was confusing a mix of compassion and guilt as love. Looking back I really believe I haven't loved her for a long time. I felt sorry for her and she knew how to use that to keep me attached.
Your friend,
Edit ( she knew how to use that so I would keep myself attached. "I can't make it without you", "you could never make it on your own without me" and "we have been through so much together, you owe me". I'm not buying that any more. )
