This morning I woke up to a text from someone I did not expect to be contacting me ever again and I was OK with never speaking to him again.  We had a brief affair, a lot of feelings were involved, I was manipulative and I know how I acted was wrong and I apologized for the way I lead this individual on but we both had to move on with our lives. 

I will admit I kind of hoovered him towards the end because I wanted to know if the messages he had sent to my partner had been read, he tried outing me to my partner at the end of our affair and my partner was acting strange but once I got my answer from him I was good, I didn't want to continue talking to him. But he wanted to see how I was doing so I went along with it. We engaged in small talk and he told me he was in a relationship and how he was so happy and how he thinks he found 'the one'. Awesome. I was genuinely happy for him, that's what I wanted for him but he was still bitter and I could tell.  He left me with 'Can I ask you something?' and I said 'Sure' and then I never heard from him since and that was back in August. 

And now I wake up to this 'Because I'm excited to talk to you.' and I respond 'Who is this?' because I don't have his number anymore and I had no idea who it was but I had a feeling it was him because we live in different countries (him in the USA and me in Canada) and I don't talk to anyone via text from the USA. ANYWAYS, he tried denying that he sent me that text message and kept saying 'I know what your phone says but you are the last person I want to talk to, if I could remove anyone from my life completely it would be you, etc.'. He kept swearing at me and just basically telling me how he didn't text me. When I sent him a screenshot of the thread he sent me one back without his message and it's like ok, you could have easily deleted the message right after you sent it. DUH I'M NOT FUCKING STUPID. 

I'm just so triggered. I wanted to forget about this person and everything that happened between us and now he goes and does this and tries to gaslight me about it and make me feel like total shit about myself. 

It's my 9 year anniversary with my partner this weekend and now I have memories of him floating around in my head and I'm so pissed off. How do I just let this go? I came on here to message him (we met on reddit) saying 'ooops I accidentally messaged you, don't know how that happened' to prove a point, your phone doesn't send messages on it's own. I messaged him just to piss him off because I know he was trying to talk to me, he just didn't want to admit it. Like get a life.  Why do people do this?
