Sorry to hear about your accident Karen.
I don't think there is anything wrong with re-evaluating the M at this point and feeling appeciative for what you DO have, not what you DON'T have.
I remember you saying D was not an option in this M and that you were in it for the long haul. So why make yourself miserable by dwelling on the negative.
I think your accident has helped you put life in perspective. I hope you can maintain that sense of appreciation for your H and have a happy M and family.
