You know its Wrong, But you still do it!!

The word is out ! Everyone knows your a whore. Everyone knows you kissed him and yet you know he has a girlfriend. You hold his hand, you kiss him, you say i love you. But you know he does it all with his girlfriend as well. Doesnt it make you wonder when you not with him and hes with her that there doing alomost the exact same thing, and your having lunch with him and he gets a text. Its her, a sad rush goes through you, you look down and he says " i chose you over her". but really he didnt. He just chose to use you to fill in his spare time. But why cant you run away ? Why cant you say no? Your hurting and if she found out she'd be hurting. What are you even suppose to do in this situation?  If you say something, you feel like you're disappointing him. But then again if you dont, someone is going to get hurt in the end , and who is it going to be ? You ! By the end of the day, he still kisses your forehead and says i love you, the reaction is a kiss back and a i love you to. You know its wrong but yet we all still do it.
