Cheating in a relationship.

I cheated on my boyfriend. I don’t know how to move on from this. Our relationship will never be the same. I will not tell him about it because it would bring and end to the relationship. Can I move on without telling him about it? I feel so much guilt through the day that it is impossible to focus on anything else. I want to move on without telling him but I’m having a hard time with knowing how.

C: Cheating
T: I’m an awful person, how did I let it get this far, I will never be able to look at myself without disgust
F: Disappointment, helplessness
A: Beat myself up
R: No forward movement

My goal is to move on, say that I’ve learned, stop hating myself, and eventually not think about it all the time as I do now, but I can’t figure out how to do that.
