Until you are at peace with any other option, I agree that A is best. Let the rawness of your heart heal a bit and then reevaluate what is best for YOU. If your wife's things being in your home contribute to your pain, then I see no problem with you sending her an email or text asking her to please pick them up.
I know the feelings you are cycling through very well. I also wondered why OW over ME? Was I not pretty enough, nice enough, smart enough, good enough in bed, a good enough cook, a good enough housekeeper and supporter of my H and mother to our kids? I would worry about living the rest of my life alone, thinking I was too flawed and unworthy of love. MWD's suggestion of imagining a huge red STOP sign really helped me through those times and got me to stop obsessing about what was wrong with me. It also helped to repeat affirmations to myself (I am a child of God and He loves me, I am a good mother, a good friend, a good person, etc). Sure, we are all flawed, and this is a wonderful opportunity to take a good look at ourselves and ask, "What can I do to be a better me?". But honestly, TM, I don't think what your wife is doing is about your flaws; this is about her. She hasn't hit rock bottom yet (although I feel that is coming soon), and unfortunately, that's what it takes in many cases to get the WAS to wake up.
Forgive me if I've already suggested it, but I think the book "Journey from Abandonment to Healing" would be very helpful to you in working through the emotions you are experiencing and starting the healing process.
You are a great guy, TM. I'm always in your corner. love & hugs...lc4
