TL;DR - In a new relationship, and guy was busy at work all last week. I did some sexual role playing online while he was busy, and now he says I cheated on him. Now he is upset and won't talk to me. How do I get him to have a conversation about what happened?

This is my NSFW Reddit account. I have been seeing this guy for the last two months-ish. We never said we were "dating", "serious", or anything like that. But we have spent time together nearly every night since we met. Things have been going great so far.

Last week, he got slammed with work, and on Sunday told me he wouldn't have time for me to come over on Monday. No big deal, but that slowly turned into the whole week. He kept telling me last minute each day that I would not be able to come over that night. So we didn't get together at all between Sunday evening and Friday evening. It was a big let down, but also I understand that life happens. Work is important. It didn't upset me about being on my own for the week.

On Monday I posted a confession about a sexy game of truth or dare that he and I had played over the weekened. I was feeling lonely, bored, and it was nice to let off some steam. The post was not intended to be anything more than that, but I should have known better. The responses and direct messages I reecieved because of that post ended up being a huge turn on for me. By Thursday, I was posting in looking for people to role play with. On Thursday and Friday I participated in a number of NSFW chats.

That was it though. I did some role playing with people online. Nothing serious in my opinion, just a way to feel desirable and keep myself entertained while he was busy with work. I really didn't think it would be a big deal. Last Friday night, I went back to his place, and we saw each other on Saturday and Sunday as well. Everything seemed fine. But then last night, I went over to his house and he was very upset.

He knows about this account. We met through Reddit originally, so it is not any sort of secret. The events of last week weren't anything which I thought had crossed a line, although we have never talked about it. We never set any sort of labels on our situation or boundaries around this kind of thing. I just sort of assumed we wouldn't have physical relationships with other people without at least a discussion first, but technically we hadn't even talked aobut that.

So last night, I went over to his place and could tell something was very wrong as soon as I arrived. He was really upset and eventually accused me of cheating on him. He pulled up my Reddit account on his phone and said that my role-playing was cheating. I tried to explain that it was just online fun, nothing physical or serious, but he couldn’t get past it. After an hour of basically yelling, I ended up leaving.

Now he’s gone quiet and won’t talk about it. I like him and want things to go back to how they were, but also acknowledge that I messed up. I hurt him. In the moment, it didn’t feel like I was doing anything wrong, but now that I know it bothers him, it would never happen again. I just want to go back to normal. Does anyone have advice on how to get him to talk? How can I get through to him that it wasn't like that? I want to understand his feelings, but I also need him to understand mine.
