Thankfully, I never got that speech. I did get the I don't love now a couple times.
For starters, I never really believed her when my W said it. It was painful to hear, but I know it wasn't the truth. When I asked her about it later, she looked at me like I was nuts. She basically said that she said those things when she was undergoing extreme emotional stress and a lot of what she said couldn't be trusted.The she reminded me of all the things I said under similar stress and said she didn't hold those against me.
But I think they honestly believe it at the time. Sadly, I think for some couples those feelings never get a chance to turn around and those feelings become the status quo.
If my wife gave me that speech, I think I'd call BS on it. I think the whole "love" vs "in love" distinction is just dumb and really code words for how they feel about the R.
