I (17F) was accused of abuse last year by my ex boyfriend (19M). We were in a two year long relationship which became unhealthy towards the end and we split for reasons unrelated to the title. My boyfriends mental health deteriorated and he could no longer be a partner to someone as he was becoming unavailable and borderline emotionally abusive. We ended on good terms which quickly turned sour as there were still vulnerable feelings particularly on my end, as I was the one broken up after enduring hurtful comments whilst having to be his only emotional support system. In the two years we had dated my boyfriend had never accused me of abuse. That all changed during an argument after the breakup in which I was telling him that the way he had treated me towards the end was disgusting regardless of his mental health issues. This is when he brought it up. He said "Remember how you used to hit me?" I was stunned and confused. I asked him to elaborate. I quickly found out that he was talking about what I saw as nothing more than play fighting. He'd crack jokes at my expense in which I would respond to with light "hitting" (I did not injure him or leave any marks). He'd laugh along with this. The most he would do would be to tell me to stop amidst his laughter, in which case I would. However, it happened on multiple occasions as I believed he was okay with it due to his laughter. He'd also make jokes about it to our friends. I also never laid a finger on him during arguments. I explained all of this to him, he told me that the laughter was uncomfortable. I asked how I was supposed to know that his laughes were uncomfortable why he had never had a serious conversation with me about this in the relationship as I would've never done it again if I knew he was uncomfortable. He told me that he never felt he could talk to me about it as I'd call it ridiculous. This was bizarre to me as I was his number one support system throughout the relationship and never once invalidated his struggles. I apologised for what I'd done and told him that he was entitled to feel upset about what happened but he couldn't just label me an abuser because of what I saw as nothing more than two people in a relationship play fighting. Recently I've been thinking about this a lot and feeling bad about it. I told my friends and his friends about it and they're all on my side regarding this issue and said his claims were ridiculous. However, I want some unbiased opinions. So, AITA? Please tell me in the comments, any opinions or advice appreciated
