I’m 15 and I really need help

I am 15. Over 3 years my boyfriend would take advantage of me sexually. He would force me (grab my head and push it down) to suck his penis and other things. I would tell him no. Once he begged me to have sex with him. He told me if I didn’t that I didn’t love him. I told him no about 20 times but he kept on so I shut him up and had sex with him. I cried the whole time. He even watched me cry as he left out the window.

He broke up with me a while back but I just feel like he used me and I feel so worthless. I just wish he was held responsible for what he did to me. What if one day he did this to other girls?

I confronted him about this and he said it was all consensual.

If I reported him would they even believe me? What would even happen? I feel like they’d think I’m being dramatic. It just hurts so much when he did this to me. I would cry every single time. I broke up with him once because of it but I just was confused. I still am.

His sister sent me this message...

And this was me to him
