Here's some tips that I've been using to get through it. Not might help, but then again, it might.
1. Remember it's HIS loss. That sounds cliched and I know it's easier to say than believe, but it's true. Don't diminish how important you are because one dude in the world doesn't dig you.
2. Trust the process. But remember you have to process it like a turd and not a word. (word processing). It's a bunch of sh!t you have to digest, but sooner or later everything will come out. Don't forget that some things, like gum or corn, are undigestible. Accept that you may never be a peace with everything that's happened, but you will be able to accept and move on from MOST of it.
3. He's not Jesus in Docker pants. I don't know if you're religious, but I have some religious beliefs. A friend told me this and it made me laugh so hard, which is something I hadn't done in a long time. It's good advice.
He's not special, he can't walk on water, turn water into wine, or raise the dead. He's acting like an arrogant fool and it's in part because he has two women fighting for him. Two people who love him and would do anything. Jesus had 12 disciples that loved him; He was a lot more humble than your husband, ya know.
