You absolutely should take a vacation alone with D6 and you should definitely be getting CS, too! See to it.
Good job with D6 telling her it is unacceptable for ANYONE to ask her to lie.
D6 was not your sign. And the one rough thing I have to say to you is this: Stop asking for signs. You don't ever believe them anyway. How much faith have you consistently shown? This is a question you have to look into your heart to answer. How much faith have you CONSISTENTLY shown, through EVERYTHING? See, the way it works is this: you stand, by faith, through a whole bunch of negative crap. You stumble, yes, but you keep getting RIGHT back up. THEN there comes a time you will start reaping joy for all the sowing you did in tears (which means, ALL THE STANDING YOU DID WHEN THERE WAS NO REASON). It will be little things at first, little glimpses that things aren't as far gone as you thought, but those little things will grow your faith. Until one day, it just takes A WHOLE LOT to blow you over.
You're now standing completely on the Rock.
As for your hope, when it is placed properly, it can not BE lost. Put it in HIM. Your husband doesn't deserve for it to be in him and that is exactly where it has been.
Get some sleep. We can talk about this more tomorrow.
