I think we all obsess at some point. I don't think about it 24/7 anymore, but when I have negative thoughts, I start to obsess. Getting out and getting my mind off of it, even if for an hour, helps. It is harder when you are wonder where you W is and what she is doing. I'm having to stop that obsession as well with my H.
I'm trying to stop my thoughts, even if I have to literally talk to myself to make me think of something else.
Try to do some GAL this weekend to get your mind in another place.
