Why does friend treat me this way? Sorry if long

1. When me and my ex were dating, my ex would say i have beautiful eyes, she would be like “i guess…” and look confused or something

2. During class, i was telling her that i tried coloring in my eyebrows kinda like hers and she said “Are you trying to look like me? :D”

3. My ex likes her and she told me he did. She said for me to guess who likes her (with smiley faces) and i said Ughh idk. She said Nvm. Then said it was my ex.

4. I started liking him again and i told my bff. She said “I asked him this one time what he thought of you and he said he didnt like you”

5. I told her that his now ex gf Tara just dumped him and tara would tell me he would be all weird and would stare at her boobs. My bff said “Haha he does that to me too and i caught him looking(:” and she kept smiling at me. So i changed the subject.

6. Last year, she said she always dreams of hating me and making me get hit by a train. She kept laughing and said she doesn’t know why.

7.Passing period, I told her that my ex asked me to homecoming and she was all like “really??” and then left without telling me. During class, she asked who asked me to homecoming, i said my ex and she started saying to herself kinda “Noo you asked him.”

8. I’m flat chested and she teases me about it. This guy kept flirting with her and i said “Its because of your boobies” (hes a perv) and she is all like “Well that’s what guys like” and kept staring at me all serious.
