I have a recurring dream about cursing out my cheating ex-boyfriend. Ideas?

Okay, I think I can interpret the dream pretty well. I know, It’s obvious right? I hate him, and I want to curse him out. Oh, and hey it works out that those are both true in real life, I just try to forget about them with my conscious mind. In fact, I hardly ever think about him, but I have to see him sometimes, and there’s no way to avoid it. (I don’t talk to him though). And then after that, I always have to work to put the thoughts of telling him exactly what I think about what he did and what he deserves to rest.

My question is how do I make the dreams stop? Is the only way to actually curse him out? Or do I have to (barf) forgive him? Because I don’t think I can right now. Or should I not worry about it, let the dreams take their course, and just go about my business? Any ideas?
