Thank you for reaching out to us here at Psych Central. I am glad you brought this issue to light.
First, let me say that if you are not in therapy that this is something you should make a priority now. The find help tab at the top of the page will help you find someone in your area. This is critical because the changes you want to make in your life will require support outside of the relationship you are in.
You dreams are reminders that you must deal with the trauma of the past. They are recurrent because the issue is important for you to make a priority. When there is an unresolved betrayal in our earlier life there is a risk that the same dynamics will be repeated later with other people.
The guardian was supposed to protect and care for you, but was only using you and your body. You have described a similar dynamic with your boyfriend “…I still feel like my body is what he wants more…it’s always all for him when we have sex…”
The goal isn’t for you to learn to love being used; but to love yourself enough to stop.
