I'm a year down the road from when she moved out, and about 8 months after the D. She's remarried, I'm enagaged. My finances are beginning to calm down, but we're currently involved in a custody change (S13's request to move back with me), so there's some drama going on there.
Of course it's never as simple as it was before, because there are just more variables in the situation, but it doesn't stay in constant turmoil forever. You'll work through the hurt, you'll detach, you'll arrange your affairs to meet the new realities post-D. Her gyrations which have twisted you up into knots in the past will somehow come to be viewed with an amused raised eyebrow and a chuckle.
So hang in there, it's going to get better, you'll regain your sense of balance and life will go on!
