How Do I Choose..? Options

[SummerSwt1527]

I have had this friend for about 2yrs. She was a wonderful person to start, then things just went downhill. She has lied to me alot. She turning into this person that i wish that i didnt know. I have recently found out that she had been talking to this boy that i used to be in love with for the longest time but who i no longer have feelings for. When i found this out i was hurt, not so much because i used to like him but because she lied to me, and thats something that i never thought that she would ever do. I think that them two "hooked up" but im not for sure. After all that, we talked and she apologized, and yes, i did forgive her. Now theres this boy, that i really like alot. I used to go out with him in middle school, but things didnt really work out because we were young and stupid. We started talking again recently and i REALLY like him. He has told me that he liked me to. The problem is that everytime my friend and the boy i really like are together she flirts with him all the time. She knows how much i like him and she still does it. Im not going to lie, he flirts w. her a little bit to, but i would think that my friend would be a little bit more nicer with my feelings, but i guess not. Some times people say that i am paronoid and im just thinking that, but i really do think that she wants him. I feel like i have a right to think this way because of the past, and i dont want to get hurt agian. I dont know what to do.
Please HELP!!

First off how old are you? Secondly, your friend just may be overly friendly. My friends boyfriend is like that, and she always used to swear that he was flirting, but he wasn't. I think that if she is not respecting you, then the choice becomes obvious. Either you are going to have to check that bitch, or just drop her...plain and simple.
