Asexuality and Aromanticism on Reddit

Am I wrong for staying with someone with a high libido as an asexual trying to work things out? Hello, I wanted to gain some clarity after having many arguments with this individual. We are now broken up but the issue is still escalating. For context I am a (22F), and the other person is a (25M). We also work together. I am leaning more towards demisexual, which in a nutshell means you only feel sexually attracted to someone you have a strong emotional connection with. It has been very hard for me to navigate the dating pool because of this. I had made it clear to him that I was asexual and explained how sex/physical touch worked for me many months ago to which he didn't really acknowledge at the time; when I brought it back up, he said he didn't remember me saying any of that and that he thought it was best to go our separate ways which I had agreed with. However, he refused to let me go; he was convinced I was not actually asexual and continued to pursue me romantically. My issue is that he has shown me many signs that he is lustful and aggressive, and I have always communicated how I wasn't really comfortable with him being so pushy about sex and physical contact, I even expressed it physically. He would constantly make inappropriate jokes, as well as touch me in public when I had specifically stated I disliked being touched that way in public. We also had many conversations about his anger management (to which he fixed to a certain degree) whenever we had disagreements or how he would treat me based on his mood. Every time I had brought up the times he would touch me without my consent he would deny to doing any of those things and always viewed our situation simply as me being uninterested in him and refusing to initiate anything. This had escalated one day at work when he begged me (spammed my phone and got mad that I didn't answer quick enough) to tell him what I liked about one of my exes, (he respected the fact that I was asexual, and was reserved: didn't treat me based on his anger. Which are some qualities I like in a partner). When I told him about it I also mentioned that if he was more like that, I would feel more comfortable being physical with him; keep in mind I never said I wanted to be with my ex, I said if he had been more reserved and understanding then I would be more comfortable. But he took that as if I had been emotionally cheating on him; I clarified later on and explained that I would be more attracted to him if he embodied the good qualities, he was still denying and even told me to fuck my ex; I had already told him I want nothing to do with my ex. To this day he has been talking negatively about me, telling everyone that I am a cheater or that I had wasted his time. He has also been causing a lot of issues at work, I assume because he is upset with me. But I have not given him reasons to act this way in the workplace; I talk to him respectfully and I do not bring our personal issues to work. https://redd.it/1uhf9mt @asexualityonreddit
