Complex #4 - D talk started / Detaching continues

[Complex]

Just read an article about the difference between love and infatuation.
What if the love between me and my W was just infatuation?
I'm sure that's what she is thinking, which makes it very real. And there's a lot of truth in it. She is right
But then I made her the promise and married her. Didn't take enough care of her, and the love died fast and through all the pain I realized what went wrong, what I did wrong. Then when she was gone already I recommitted to my M, started to love my W the way I should. But it came too late and maybe her love really was just infatuated.
True or not, as long as she thinks that I have zero chance to save my marriage.
She basically first has to feel like I'm a good friend and then fall in love with me again.

Painful insight...I don't know what to think, it's a serious though, or if this should change my plan. Phew..
