My ex breached bail (uk)

Ok so this is a long one but please bear with me. So in April this year my ex turned up whilst I was at a friends house having a bbq and attacked one of my male friends. I had tried to stand in the way and as a result he was charged with common assault against myself. He was also charged with section 18 wounding with intent as he attacked the lad with a baseball bat and ruptured his spleen. He was arrested that night and released on bail 36 hours later with the restriction to not have any direct or indirect contact with me. A few days later I bumped in to him, drunk and seeking answers I agreed to go home with him, we talked and the meetings became regular. At the time my mental health was particularly poor, and he convinced me to retract my statement against him. This became the relationship we had once had, however I quickly started to see how manipulative he truly was. He was emotionally abusing me and playing on my fears of him turning against me to keep me there. The whole thing was pretty fucked up, I didn’t see it at the time but since the contact stopped in August I can now see it was all manipulation to try and get me to help him lessen his sentence if found guilty. I’m deeply ashamed that I let myself slip in to such a low mental point that I was being exploited and didn’t see it until after the events occurred. I have now written a statement confessing all of this and I’m about to hand it in to the police telling them he’s breached bail, intimidated a witness and has been domestically violent towards me the last few months. I’m scared shitless about the fact I lied to the police initially when they received reports he’d contacted me. Please send me some encouragement cause I’m like 50/50 whether to hand this in or to just go to trial in November and not say anything, purely out of fear of what he will do to me if they re-arrest then re-release him after I hand this in. Please help, anyone on here that knows legal stuff and can help me?
