Its all about the vibes.... If you are not an empath/empathetic person you will NEVER understand this. It is a blessing and a curse. .
It is difficult to explain, but we pick up on vibes. So you can SAY one thing, but something inside us just KNOWS when you mean something else. Maybe not right away, but the more involved you become with someone the easier you sense things. The bigger the attachment the stronger we can sense what's up.
I knew when my ex slept with another woman to the hour and I was 500 miles away. It was confirmed by him. And so many more instances....Again I can't explain it, it's just the way it is. And we can't turn it off. That's the curse. .
