My family wants me (24f) to have a relationship again with my brother (19m) who attacked me. I don’t know how to move on and make them happy?

TW: physical abuse

Two years ago my brother beat me up so bad he possibly snapped my ribs although this was never confirmed with an xray but now after seeing multiple doctors for persistent shoulder and neck pain it has been confirmed I have a spinal injury caused by him attacking me.

What happen in short was I used his phone charger when he told me not to which I thought was a joke at first cause he wasn’t using it and I didn’t see why it was an issue for me to use it when I didn’t have one as we did not live together and I had forgot mine. Following this he beat me for around 5-10 possibly 15 minutes (I can’t remember clearly maybe because it was traumatic for me) until he pushed me off his bed he was beating me on and fell ontop of me (he was around 110kg) and because I fell onto my side in an awkward position, the force must of caused my ribs to snap and when he heard the noise of what I assume was my ribs he got a fright and stopped beating me. The whole time leading up to this I was crying and screaming for him to stop. I already had a lower back injury at the time from the gym and tonsillitis I was on antibiotics for.

My parents are divorced were both at home at the time coincidently but ignored my cries for help. I went down stairs after to tell them what happened and they were aggressive towards me and dismissed my pain. I went to the ER alone in an Uber as no one would drive me or accompany me. I spent the night and no one attended to contact me or ask if I was okay.

My brother has faced no consequences for doing this to me. They bought him a car and paid for him to have driving lessons which I never got even to this day. Also last Christmas I spent it alone as my mother spent it with him and I didn’t feel comfortable being around him.

Now I may need surgery for my spine as the damage is still causing me pain all the time later and they both have asked me to have a relationship with him again but I am so upset and I don’t think I can forgive him. I really need some advice please as I think this is a very unusual situation.

Also I don’t believe he is sorry as he hit me and strangled me prior to this just not as bad and never apologised those times either. And the attack happened when I was 22 and he was 17.
