Fiancé always goes into victim mode during arguments

My fiancé and I are having a doozy fight over the past day or so. We currently aren’t speaking at the moment. Whenever we have an argument he ALWAYS finds a way to make it out that he is a victim and anytime I try to say my part and tell him how I’m feeling it’s always me “coming at him” and “attacking him”, when I I’m literally calmly expressing my feelings about the situation. Every single fight we have, I go to him to try to resolve it, even if there’s pushback, I will go to him again in a few hours and try again, it’s always me chasing him to end the not talking. Well this time, he is completely in the wrong, he kept something big from me and blew my trust (financially - see my last post for context). Anyway, he’s done the victim thing yet again and I’ve said nup, sorry, I’m not taking that this time and I’m not coming to you to try to resolve this, you need to come to me. So the not speaking just carries on and I have no idea how long he’s going to leave it before coming to me, if at all. I don’t know how to handle this, I feel like it’s manipulation in a way and it is so frustrating. Any advice??
