I think the "wave" of emotions is normal when we're going through this. I know I've been going up and down for months. The last 2 days I've felt great, 4 days ago I was miserable and locked myself in my office most of the day and only reason I didn't reach out to W (and make a huge mistake) was because of these boards, a week and a half ago I was so angry with W that I would even say I "hated" her for a few days. From what everyone tells me it will get better so we just have to ride the wave of emotions.
I don't think it's bad to feel hurt. It's normal and probably healthy to allow us to heal. You just have to accept it but not let it control you or what you're doing. Try to get out and do something to get your mind away from sitch for a while (see a movie, read a book, exercise until you can't think anymore, etc...). Earlier this week I went the extreme exercise route and I was too tired to give W another thought.
Keep your head up and continue to work on yourself.
