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!!

maybe she does it without realizing it. i've been with someone for just over a year plus i used to be in a 3 year relationship && a 5 year relationship..then i have obviously dated others in between. anyway..what im getting at..is that almost anyone who knows me (friends, family, etc.) all tell me that im a huuuuge flirt && they get jealous && whatever. i, personally, never think i'm flirting. i think im just joking or like the person before me said..be "overly friendly." my boyfriend thought that i liked two of his friends because i was always laughing and talking with him a "flirting manner." talk to you friend about it..if you still get irritated by her or what have you..then get new friends..its life.
