Bipolar ex boyfriend anger

I’ve dated my ex on and off for 6 years. From the very beginning things were off to me in the way that we start dating and how he left his ex of two years out of nowhere to be with me. With the ups and downs of his moods we’d never be together in a relationship for very long, once he experienced an episode one of us would break it off and go our separate ways but that wouldn’t stop him from occasionally ripping me to shreds on social media & getting into a new relationship within weeks which hurt when we were dating so publicly. Eventually he gained so much success and the women followed. He vowed so much of his love and appreciation for me of helping so much with his success I thought we’d be together forever even with the on and off situation. Our last time dating was terrible but it lasted much longer as he told me he was on his meds and healthy. Before we even got back together he lost his temper with me and threatened to hit me before he threw me by my hair and took my phone and car keys... after the fight he decided he wanted to have make up sex and that we should get back together and we did. He tried to make me comfortable in the relationship but so much pain over the years I just couldn’t handle it. Our last breakup was terrible and I lost it, I lied and said I cheated and didn’t love him and had no care for him whatsoever out of complete rage for yet more time and money wasted on a vacation. He ended up paying me back but I could tell he was upset by the things I said. He recently contacted me after 6 months, in between that time I wrote him an apology to clear things up that I thought he received. He told me he needed my help and out of the kindness of my heart I agreed. It ended up all being lies and manipulation to get me to be around him again and we ended up having sex and spending all this time together and going on dates & spending time with his family. Once he went out of town he start picking fights with me and then start saying we’d never get back together because of the things I said, and he ended up actually having a girlfriend. I went into another blind rage and told her everything and he would say awful things to me. “Wait until you see my next ***** you’re going to be sick” and that I was doing him a favor and he didn’t care and never loved anyone anyways. He made comments about how I was literally nothing and how much he hated me. I felt like he set me up for revenge and he refuses to say he did anything wrong or apologize. I know he’s unmedicated and he was drinking and taking some drugs here and there but he’s never been this type of evil person and said these types of things to me. When I told his gf about what he did he just start blowing my phone up to talk and play games instead of reaching out to her which bothered me even more. A few days later after he blocked me on everything he emailed me for some songs I played for him when he was here and haven’t heard much from him since. He seems manic at this point but honestly I just feel like an idiot for giving him my energy at all. I’m sure he’s back with the girl, insisting he was back on his meds. Over the phone he told me he lied about ever being on his meds and hasn’t been on them since 17 and I had no idea who he was. Telling me he was a psychopath and that I should block him. Did. Lol. I’m not sure who this person is anymore after 6 years. I wasn’t under the impression we’d be getting back together but I thought we had more respect and love for each other than to do this. He’s told everyone that I’m crazy and how much he hates me so I doubt I’ll hear much from him. I just wasn’t prepared for this.
