If you have NOT gladly and freely consented to and participated in sexual activity -- if you have not in some way said a big yes and wanted to keep saying a big yes -- and someone else had sex with you anyway, that is rape. No matter what ANYONE tells you, it is not your fault. There certainly is fault, but it lies with the rapist, not the victim.
Never believe: "I love you, it will never happen again." It will happen again. The tears don't matter, the bruises don't matter, the broken bones and ER visits and warnings from friends and relatives don't matter. Those scars that we bury deep inside us, the mental and emotional scars that we try to pretend don't exist -- they don't matter. It will happen, again and again and again, unless someone puts a stop to it.
