Isn't it funny how sometimes it isn't until an option is seemingly taken away that we realize how much we want it? Maybe this is what needed to happen for you to see that DE IS right for you... That in itself is a very positive step.
As for your DH, he's obviously going through a lot, so I'd give him a little time. Since you have to wait to do DE anyway, luckily, time is on your side with this.. My guess is that he'll come around eventually, but with everything going on right now, he's not seeing the positive side of anything. Just try to be as patient as you can and let him work through it in his own way.
Hugs to you, Emily!
