The unknown can be very nerve wracking. Sounds like you and husband are handling this together though, which is a good thing. Have a plan in place that the two of you can agree on just incase things start going a direction you don't want them too.
I think the most important thing for you to remember when he gets home is not to let him manipulate you. Anything he asks for, or to do, you don't need to answer right away. You should take time to think before you respond to anything.
Hopefully it goes smooth and within a few days he'll be back where he came from. I'll be thinking about you. I'll be on my way to Florida, but I'll try and check in from my sister in-laws computer a few times next week.
