[hocus pocus]

It doesn't sound like you're making it up in your head. You were under the influence and you kept asking him to wait or slow down but he didn't and that's assault.

You said it doesn't have much of an impact on you but that's okay. Everyone reacts and copes with things differently and they do it in their own time.

The fact that you're reminded of him sometimes (like with the cigarette breath) is normal though I imagine it is uncomfortable. Maybe when your boyfriend smokes you can leave the room or do something else? For instance, you could go smell some perfume or some kind of food instead.
