I found out my [28M] fiancee [28F] cheated on me.

This is the worst thing I have ever written. To be completely honest, I don't even know how I feel right now. I'm more numb than anything.

I [28M] just found out that my fiancée [28F] cheated on me. I won't go into too many details about how I found out; it doesn't matter.

When I first started dating my fiancée, I told her I only asked one thing of her: if she ever wanted to be with anyone else, she should tell me. It didn't matter when or where – she could call me, text me, whatever she wanted. A simple "we're over" would have been enough. I wouldn't ask, I wouldn't push.

I just didn't want to be cheated on. My father suffered when my mother cheated on him. And that destroyed him.

I didn't want to go through the same. But here we are. I didn't ask alot. I didn't need a lot. I just needed honesty and even that I couldn't have.

I broke up with her, but she's trying to explain herself. Saying she wants to meet me to talk. I can't. I can't see her right now. It's still too raw.

But she keeps pushing. Which is why I'm here. I don't know what to do.

Should I give her a chance to explain? It won't change anything. I don't want to be with someone who can't even give me the only thing I asked for. But I still love her. I can't lie and say she doesn't mean anything to me. She means everything. Which makes this all worse.

TL;DR: I found out my fiancee cheated on me, we broke up, but she wants to meet to explain herself.
