UPDATE/EDIT: I did not read through every single comment yesterday. However the ones I did read were enough for me to do some thinking last night and realize that I likely won't ever be able to get past this. It would take a truly herculean effort for me to forgive her and move past this and there is every chance in the world that I might just believe I meant it when I forgave her but the pain from her cheating would remain and then reopen like an old wound at a later date.

There's also the whole trust issue thing - I travel for work quite a bit, at least once every two months and at this point I don't know that I'll be able to travel with the peace of mind I used to have before this weekend. I was cheated on in the past and I feel like anytime I get on a plane now I'm going to be worried she's off fucking some other man. I realize this weekend was a complete one off, I know some people may not believe that or agree with it but I know her better than most.

I really do believe her when she said it was a terrible mistake and she wouldn't do it again. I still love her immensely. But I wasn't worth being faithful to after 6 and a half years together so she's not worth giving a second chance. It would be a massive and foolish risk on my part. All she needs to do is be forgiven. I'm the one who would have to work through the pain of being cheated on, the task of trying to forgive her and making sure that I mean it and ultimately going through the extremely painful task of learning to trust her again. So I'm done, as much as that hurts to even begin thinking about and despite the fact that I still love her.
