If that's his attitude after all you're d-days then maybe a calm, "you need to leave or we will" should be enough.
I'm so sorry he's still hurting you.
I ask because, considering the way he's acting (he's still an active wayward), and since he's HOME acting this way, the 180 can be extra-challenging (but even more important right now). If you need some time and space to YOURself and he's a good father, let him watch DD while you take that time and space for yourself. He'll be actually taking some responsibility by watching her, she'll get time with him, and he won't be able to bother you or talk to the OW(s?) if he's being attentive to her. You'll get some time off.
Or, you and your DD can find something wonderful to do. If he's in la-la-land, then spend time with her instead. It might feel grounding to both of you. How old is she? Does she know about what he did?
You don't have to say anything to him. In fact, it might be better to let him deal with his delusions without you as an audience. Just keep taking care of yourself, come here when you're struggling. He is an active wayward who does not appear to want to change.
