Does she actually know what shes doing to me?

Oh I'm really sorry that I have to tell you this...but if i can't say i am absolutely sure,then there are 95% chances that she is still in love with her ex-boyfriend. But even if she isn't, she's just not straight with you. You sound really good, don't let her treat you this way. You may love her, but you also have to love yourself or else you'll get hurt. You don't deserve this!!! You're being her victim...
