I'm sorry, I didn't answer some of your questions.
I believe divorce is morally bad. i made a commitment and I plan to stick by it. I let my W down a lot, which means I failed that commitment, and now I'm afraid I'm being punished by God or Fate or something for it. But I take my vows seriously and always have.
I'm having a problem letting my W be with her depression. Boy, do I want to make her feel better. I'd do almost anything except sign the divorce papers...
