Is this 'normal'?

I've been complete NC, including googling him and looking at his dating profiles and his wife's blog. And I feel worse everyday. I am in therapy, started meds and running again and have read as much as I can find. I'm making an effort to move on and forget him- and it's NOT happening. I dream of him, think of him all day, obsess over the fact that he made me a fool, it was all a game to him and I didn't know it was a game. He's seeking out people to destroy when he has a wife and kids at home who adore him. I think about his wife and how I'm now forever going to be someone who slept with a married man. That's not who I am, not what I believe in. It's almost unbearable. This man has destroyed any self esteem I had left and I don't know what else to do to get it back and to forget him. The worry that I won't be able to move on is too much. Besides the physical stuff I feel like he emotionally raped me and it makes me sick and so sad. Is it normal to feel weaker and worse each day???
