I know it's rough, but you've been at the DB'ing a while and I'm confident you'll bounce back quickly. Just remember that even though it's been 8 months you STILL can't believe anything she says and only half of what she does. That was only how she felt at that moment in time, who knows how she'll feel in a week or month or year.
We really don't get just the one BD, our sitches are filled with multiple BD's. First the big one, then smaller ones regarding separation, threats of D, D paperwork, division of assets, etc. etc. As time goes on we get more resilient and bounce back from the smaller BD's faster. You can do this!
