Yeah others have mentioned this a lot on this forum, but here's the scoop. People don't just switch off and stop liking the SO after someone suggests it. Your post was fine but people don't listen or won't listen until months and/or years after the fact, because they are in it and going through it. They would rather fight tooth and nail to get back into some relationships where they thought they were in love. It's a process they have to go through obviously and then in hindsight, only until time has past, where they come to the realization of your post that they wasted so much time and money for someone who never pined after them. Or they become lurkers for a time afterwards, still getting readings about the ex.
