Bea, I couldn't agree w/you more in re: how we are equipped to deal with this stuff. Our spouses didn't have the toolkit to deal w/what life threw at them and what better way to handle the difficult situations...but to run.
I do hope your xh settles down and leaves you alone for a bit, but I'm not holding my breath on that one.
Have a great week!
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
