I am sorry that this has happened to you and I’d like to challenge what you are calling strange love. It isn’t love — not at all. I am not challenging your feelings because I understand the confusion. You didn’t have a choice in who your sexual partner was going to be, did not want it to the point of having the police involved. This is about sexual abuse and the resulting reactions that happen. He did something to you at an age where you should have been protected from him. Feeling bad for him, wanting his attention, and being confused about all of this isn’t a healthy love. It is often some of the complex feelings involved after abuse.
I believe some individual therapy would be good for you to engage in as it can help you sort through these feelings of “strange love” and revenge. The find help tab at the top of the page can help you find someone in your area.
