A step in the right direction, I think

Well, I deleted my ex from Facebook.
I saw a picture of her that was uploaded to Facebook of her and her boyfriend, and I realized that being friends with her does nothing but anger me. When I see stuff like that it makes me sick to my stomach so, after some deliberation I decided to delete her.
Its tough for me to accept this, but she really doesn't care about me any more, and I guess once I realized that I deleted her. I think I have finally had the last straw with her, and I want to feel like I have the upper hand on her for once.
It just makes me so mad, because by deleting her I am acknowledging that we wont be friends again. I feel like I am supposed to feel better but I really dont, because having to delete eachother and completely cut contact wasnt what I wanted.
