Family & Friends

I'm her best friend, but she's not mine?

This girl, and I use the term forcefully, likes to call herself my best friend. But I cannot see her that way. She is a flake, and there's a history of her consecutively letting me down when I needed her. She's dating a good friend of mine, and my husband and I often go on double dates with the two. I basically have to be around her. Because of the good friend she happens to shagging, I asked her to be a bridesmaid in my wedding. We went to get her fitted, and at the counter to pay, she informs me she's broke. I bought her bridesmaid's dress, as the cost of almost not getting my wedding dress paid for. Two: she was, as I mentioned, a bridesmaid. She didn't show up to my bridal shower, and had no real excuse. Example three: on day one of our honeymoon, we flipped our car. Totalled it out. 10 hours from home. My dad and stepmom came to get us. When we finay get home, the girl and my friend come to check on us, and the entire time she's talking about HER car wreck, how she knows how we feel. She ran a red light going about 15 miles an hour. We rolled twice in a snowstorm. She doesn't know how I feel. Example four, and final for this year so far: she makes me fat jokes. She is a tiny girl, and I am a full-figured woman, 3 months pregnant, and have been sensitive about my weight since I was a child. She called everyone in my house fat one night, 30 minutes later, during a shooter fest on our 360, I got to a sniper nest first, and she called me a fat bitch. A loose comment I am aware. But I get uncomfortable if you say "fat" around me, and all my ACTUAL friends know that. I have no idea how to handle this situation. She's clueless about how I really feel, and I know its wrong to continue leading her on this way. Then I remember how she hurt me, and the devil inside smiles that this might hurt her back. I need advice.
