hi billypilgrim
I feel like my only option here is leaving - and it seems like I've already been left.
you sound remarkably well-composed for someone in your situation. it's really admirable. when my wife bolted, i was in danger of my stability. it was a slow process to regain a sense of control over my conditions. if there is no reconciliation (which sounds unlikely if she signed a separation agreement, though that's not a divorce) i would only advise that you don't
rush forward. how are you tending to yourself? do you have support?
It just seems so impulsive. Ending this marriage just seems all too easy for her and that's what I can't understand.
it probably was impulsive. that's the disorder. i too wondered how my wife could chuck a marriage, even with problems we had, and move directly in with someone else. "i like what i have and it's not a fling." thanks for sharing, wife!
have you had a chance to read the resources on the site? here's an introductory video:
