In my view the reason you were reactive was because your boundaries were crossed and you weren't ready to R. Likely he wasn't remorseful enough and maybe didn't atone as you needed.
His A blew up your marriage and put you through hell.
I have no truck with cheaters none, zero.
I had my screaming banshee phase too, it was awful and not good, I believe I have resolved it, although I will need help on it from time to time so it doesn't affect my life. It's quite usual after a spouse has had an A. He blew up your M by having an A and after that you may never trust him. That was also me, something you learn may tell you that you were correct. Entitled peeps stay entitled.
He is in the guiLt phase it may not last for long so use it to advantage.
I am concerned that you are working and living somewhere which might cause you breathing issues. Can you work in a library or coffee shop sometimes?
Extreme self care Nicole, extreme.
It's going to be ok.
