Advice quick! Partner on OnlyFans!

Okay quick back story ,

My partner and I are 18 and 20 and I found out 5 months ago going through his phone (not to find anything just scrolling) that he had a secret only fans account. (Cause we have a joint only fans that we use for crypto)

I confronted him and we sorted things out but obviously I’m very hurt as he knew I wasn’t okay with it (obvs why would he have to hide it) he said he was using it as porn thinking it wasn’t any different (cause idc about porn I use it too) and that he deleted the account straight away after.

But now 6 months later it was on my mind and I’m thinking. There’s a chance he didn’t delete it when he said he did and instead was using it the whole time ..and when I confronted him through text while he was at work he deleted it before he got home ..

Now my question is I really wanna say something and bring it up before bed. We’re in a good place rn and this has already been sorted but it’s on my mind and I really wanna pick a fight a little as it’s really upsetting me.

Is this a waste of time ? If it’s already been sorted should I leave it in the past? Is it even worth asking what I already know? What would you do seriously? Am I being petty and starting drama for no reason?

Thanks

Obviously this really hurts me please be nice I’m trying to sum it up as short as possible.
