Drop her out of your life. She's no good. Seriously, you don't need bullshit friends like that. I went through the EXACT same thing. We had a fight (which I started), became friends again, but then I realized I didn't like her at all. I mean, when she came around I felt disgusted and almost threw up a bit in my mouth. I just cut off all contacts with her and it feels great to get that load off my shoulder.

It's been months since I've done that and at first I thought about her everyday, like you did, but that faded after a few weeks. I rarely think of her now if at all, and that's the way it should be.

Yeah, just move on. Simple as. You can go the way I did, by telling her she's full of shit and can go fuck herself, or you can find a nicer way to do it.
