Dear Heartbroken - let me translate something from the WAS language,"alien-speak", for you:
whenever you hear "I don't know" you can substitute "I have GOOD NEWS FOR YOU" in it's place. It may not sound like it but that's esentially what it means: not knowing what they want is MUCH BETTER than having some idiotic notion that they know exactly what they want and are leaving to get it.
I realize that what you hear is "I don't know that I want YOU" but let's substitute "OW"! "I don't know that I want OW" has a much more positive ring to it doesn't it? And it's a realistic translation, you have a 50/50 chance don't you? Just keep translating that language to your advantage...breathe..."you say potatoe, I say potahhhhto"... "I don't know that I want to screw up our future" "I don't know that I want to rip our family apart" "I don't know that I can keep doing this stupid stuff"
I have a shovel and I'm not afraid to use it. Stubby
