 I just want to reinforce it if he did tell you this, that the way, one rule of thumb is if you have doubts that you're in mortal sin, that you're almost certainly not a mortal sin. You could even put it this way. If you wonder if what you did was a mortal sin, you can say it wasn't a mortal sin. Because in order for it to be a mortal sin, you would have to know, oh, this is a mortal sin.
