Throwaway for personal reasons. I have been with my current boyfriend for over a year, and I would say we are relatively happy. The events I'm asking about occurred a few months ago but I'm asking since I still wonder and am worried about it.

In around February of this year, a huge argument ensued based on something I said in December, but I don't remember saying it. We'd gone out with a few friends for some drinks (I would like to specify that I had ONE drink here), and I was asked if I would sleep with some really ugly guy for £50 million. The guy wasn't specified, just someone who would be really unpleasant to have sex with. I apparently said I would. The thing is, nothing was said about it later that night, no argument, nothing; my answer upset my boyfriend but it wasn't brought up.

Fast forward to February. I was watching a cooking program and idly mentioned how good it would be to be paid to judge tasty food like that. He asked if I would still do it if I had to eat food I didn't like and I said probably if I was paid enough. That's when it blew up. He was shouting - so loud it made me cry - that I would do anything for money, and brought up what I'd said. He was saying I was disgusting and I was essentially a prostitute, and I maintained that I don't remember. The argument was so bad that he wouldn't speak to me for days and made me change my profile picture on social media to my dog because he was too disgusted to see my face.

I want to make clear that I don't necessarily deny that I said what I said, as I do have a bad memory and that at the time, I could imagine I jokingly said something along the lines of it being economical. I could well have said it and I could see why it upset my boyfriend. The issue still gets brought up sometimes, that I'm driven by money because I said that and it is still used against me, but we are more or less past the argument and he has since stopped shouting at me the way he did, as I told him he frightens me and he broke down and promised not to speak to me like that again.

I just really don't remember these events, and I'm worried they were made up to use against me and manipulate me since it's still brought up sometimes and I just go along with it.

tl;dr: don't remember saying something which caused argument. Is my boyfriend manipulating me?
