I talked to her about it later that night and she told me "I wasnt flirting" I think she was was she not?? I love her to death but I cant deal with that im going to end up hurting someone... Some one just please help me

awww.
have a serious conversation with her and let her know that your serious and you want yher full cooperation. tell her to stop flirting and if she claims shes not flirting tell to stop doing what shes doing to hurt you.
tell her you dont feel comtorble when she acts like that towards other guys and for her to stop.
if she does it repeatedly after you asked her to stop, then im sorry to tell you, but shes just not that into you...or she just cant help it.

LISTEN. SHE MIGHT DO THAT. YOU HAVE TO TRY AND FIGURE OUT WHY SHE DOES IT. DO NOT ACCUSE OF DOING SOMETHING SHE WILL JUST GET PISSED OFF. HAVE A TALK AND ASK POLITLY TO STOP. IF SHE DOESN'T AND IT BOTHERS YOU THAT MUCH. AND SHE DOESN'T QUIT IT WON'T WORK OUT. IF SHE IS NOT WILLING TO CHANGE SHE IS NOT IN LOVE. I KNOW THIS because I DID THE SAME AS HER... ALL THE TIME. I FOUND THAT SPECIAL GUY AND I MADE IT WORK BECAUSE I KNEW I LOVED HIM AND DIDN'T WANT TO LOSE HIM.

it's not a matter of trust if she cared about your feelings at all she would not be flirting with other guys thats a form of cheating as far as im concerned, unless its part of her job to flirt I don't think so. If you talk to her and she still continues dump her, you deserve better then that

How can you love someone when you have trusting issues with them... that's like my parents saying I love you but can't trust me..then where is the love at? maybe under the couch or it got flushed down the toilet... listen, if I knew my man loved me I would respect him all the way like to the point if I knew dudes before you or in class I would just talk in general but no touching or love talk.. you feel me? I mean why the hell she's touching other dudes.. if she's doing that now imagine later... if I were you I would leave her..because she's causing you too much drama..and as for you don't get into relationships until you solve your trusting issues & remember the mistakes you did in the past so when you might the one you love you won't repeat it.. and by the way you really want to get her attention, then avoid her for a while and don't call her & then see if she calls..if she does then she has something for you if not..then avoid her you don't need this..

well if she dosent stop then give her a taste of her own meds and YOU go around and start flirting with other girls...it happened to me once, (what does she say when you ask her) and start directing a lot of your attention to other girls...shell realize what shes doing and hopefully stop but if not then she obviously has a defect and you need to break up with her FIRST... just be like ( in your own words) look I dont like where our so-called relationship is going and just dump her and hook up again ASAP

the reason you need to hook up fast is to let her know that she didnt phase you n that you r stronger than that
