I told my H the same things you did -- no second chances. The main reason I gave him, though, was that I felt that if could hurt me again the way he hurt me this time that I would have to believe that he not only didn't love me, but that he didn't even like me anymore. I made myself very clear on that issue. H said he'd rather kill himself than go through this again. I believe him. The trust is coming back - slowly.
