Its better to kick her in the pussy and dump her.
Seriously man if you look at it then she have no respect for you. And love without respect is like angel with one wing - it cant fly. Anyway you should go out together, you cant trust het as you have found out already. You have to man up and stop letting her doing this to you.
"Wow... he let me treat him this way, he let me do this to him. He is afraid to be man, if he lets me do this thing to him, what else will he let me do? Will he protect me when I need him? Maybe not, if he is afraid to put me in my place. How can he protect me from another man when I need him? He is not the secure guy I thought. He looks weak to me. I can manipulate him now to do what I want him to do. I can get away with anything now. I can do what I want. I'm in control of things now. He is not. He will jump through my hoops. I can tell him what to do. How can I take him seriously anymore when he won't stand up to me? He is not a challenge, maybe I need to look for another guy. His insecure behavior really disgusts me. He is not a man that I need. I have to let him go. I need another guy. He is gone, we are over."
Doubt kills more dreams than failure ever will
