Is it just me or was my ex gf a total b**** about this?

Okay so I had a mental breakdown in school and went away for a while. Anyways, I never told her where I was (I was in therapy) and apparently while I was away she found out about my smoking and drug use. I had never told her about it, but was thinking about quitting smoking for her. Anyways, she started telling people she never liked me anyways and she was in love with her guy best friend all along and was f*** buddies with him. She said she couldn't wait til she could break up with me. When I came back into town, I went out to hang out with our friends, but she didn't show up. That night, she called me and tried to do it over the phone, but I wouldn't let her. I told her I would be at her house the next morning. I showed up, and she broke up with me. I asked her if this had anything to do with Kyle, her best friend, and all she said was "This isn't about Kyle." Anyways, I left and I would see her around school a bunch, and say hey to her, but she would always ignore me. Most of the time, she was with him. Anyway is it just me or is she a skank a** b****?
