It Makes Me Mad That My Friend Likes My Ex-boyfriend. I Don’t Know What To Do?

this is a really confusing situtation so i’m just going to explain it with a few points here!
1. the guy and i are friends, we go out. we break up.
2. broke up with me because he THOUGHT this other girl (my friend, we weren’t friends at this time!) liked him. she didn’t have feelings like that towards him!
3.we were still really close friends for a really long time after the break up.
4. we had a stupid arguement.
5. no longer friends. still hated the other girl.
6. met the girl responsible for ruining my relationship. we have a lot in common. we’re now super close friends.
7. swore to me that she didn’t like him like that. she’s known him since elementary school.
8. i told her i’m still not over him…. seeing his face everyday SUCKS!!
9. a really sweet guy just asked her out two days ago. she said no, but couldn’t tell me why she rejected him.
10. she talks about my ex a lot with me. what they talk about, she sends me forwarded texts, etc.
11. she likes him now, i can tell. he’s always liked her.
12. i’m worried because i don’t want them to go out because i still have feelings for my him!
13.we’ve talked a couple of times and he smiles at me a lot a school. we’ve tried to re-kindle our friendship, but i’m to shy to go up to him and just start talking! he doesn’t know what to do either!
14. my friend isn’t shy at all. if he figures out that she likes him, i’m screwed. he’ll go for the easy bate.
help me! i want to start talking to my ex again because i miss him, and i want my friend to snap out of it and realize that she doesn’t like him! she can get a million guys… why’d she have to choose my ex-boyfriend? i just feel like crying and calling her a selfish b*tch and him a jerk! what do i do? should i tell my friend how i feel? should i keep trying to move on from my ex?
