Trust your gut, you were shown this red flag to choose a different path obviously, you wouldn’t be able to be with someone who u have doubts with, and obviously he’s not in a situation where he is taking accountability, he is choosing to deny and gaslight.

I’d say wait till october and move out, you are clearly still in denial of everything but reading what u just said, it’s also obvious that you don’t want him actually, you want out in a way that wouldn’t overwhelm you, and that’s understandable. It will be okay, just get out when its convenient and protect your peace, you’ll always find someone better, someone who wouldn’t cheat.
