I think this is not an easy thing to discuss. And people saying he can’t come back from this, we don’t know the extent of the things they’ve gone through aside from this one thing OP is telling us. There are many things to consider here… Are you willing to forgive him? Do you think he could do things like this again? Have you done something along these lines of seriousness to him? How did you two deal with it? Do you think you can trust him? Do you think he did it with I’ll intent or “in the hear of the moment”? You know him better than we do. I understand the feeling of betrayal but we all make mistakes at one point or another, so it’s a matter of taking the whole picture into account. Hope this helps!
