Let me just express this one very strong opinion. I don't believe in the heat of the moment that people say things they don't mean. I fervently believe they DO mean what they say - even though they might later regret it.
Which just goes back to my belief that you can't take words back. Ever. Once they're out there... consider them like space trash, always hovering out there someplace...
Romance is sexy - big mouths, not so much.
