It's important to remove emotions ...
It's very important to remove emotions. Yes, this would be extreme hard to do when blindsided by this confession on the day of the wedding, when your hopes and dreams are thinking quite the opposite.
Reacting with a knee-jerk is not what you do, and you do not use the situation to embarrass the fuck out of someone, regardless of what you think they deserve. In fact, it's a real test of how much you really care for them, even if they have not reciprocated that care in what they did. So there is no sense to bombard them with a total disregard for their emotions, even though that's what they have likely done to you.
So here's the reality of the situation to look at ...
1. Yes, she was honest, may be positive (I stress "may")
2. No, this was a poor decision on her part the night before, which she already recognizes was a mistake
3. Her weakness come honest is setting a horrendous precedent if you accept it as-is, it may repeat
4. The timing and pressure of the wedding may mean her guilt and resulting honesty may not be as sincere, and a hastily made
5. Now is
not the time for either of you to make decisions
First and foremost, the wedding should postponed. The reasons should not be given and you should stand your ground without saying otherwise.
In fact, now would be a good idea to go ahead and take your "bride-to-be" on your "honeymoon" trip to discuss the situation, even though you are not married. Fuck everyone else or their inconvenience, you two have serious issues to resolve before you commit. You should thank everyone for coming, and retreat with your bride-to-be -- again -- no further explanation for now.
Once you have your bride-to-be on the trip, it's time to get to the bottom of the issue. Wait until you two are alone, not in a public area where embarrassment may drive one to leave, or on the plane when everyone is listening. Tell her you want to wait until you are both alone to discuss and she should find something to keep herself busy for the time being. If all else fails to keep her from yapping, a hug may work and telling her you're still her friend she can confide in for now.
Once alone, start with ...
1. Does she want to sleep with other men than yourself? Get to the bottom of that, it may be a core, hidden "value" of hers that she still lusts for. If so, then you need to decide if you are willing to deal with that.
2. If she flatly denies wanting to sleep around, she needs explain why. Get at those emotions and don't let her make excuses. What was she feeling. How "good" did it feel? Sometimes she does want to sleep with other men and she has not come to grips with it. Again, revisit if you're willing to deal with that or not. It's going to be difficult to prove to herself (let alone you) otherwise, and when the "next weakness" may be -- if she hasn't already been doing it before when you were together (likely if she's still in denial about her lust).
3. Harp on the irresponsibility of sleeping with someone else on a whim, and how that could endanger your health and being. Really harp on this, and how that "trust" has been violated even if you are willing to overlook this. You want a wife that care for your relationship, not herself above all, especially if you're going to look past her transgression and at your unity.
4. You need to tell her your values, in their entirety, and tell her she either accepts them as her own, or she needs to find someone more compatible. She will spew "love" and other, arbitrary terms, but you need to hit on those values. Tell her she would be much more happy if she cannot agree to those values and honestly choose not to be with you. This is very, very key.
And here's the key in the end:
You have to be 100% satisfied with her and her answers. If you're not, you're already out from under the pressure of the situation (at the alter) and if you really find you love her at a latter date, you can always marry her. But for now, if the answers aren't there that you even remotely like, you know the answer, and she must understand. Again, not having the pressure of the alter in front of you, it will be much easier for both of you to wait.
As far as making love to her on this non-honeymoon, it's your choice -- although remember she just slept with a stranger. If she wants to, remember that her emotions are erratic and it may not be true. If you just want to have her sexually just to have her sexually, then be honest about it. If you want to enjoy other women on the trip, then say that, but don't do it out of retribution or "hey, I could have picked this hot woman." If you want to have fun, push a three-way on her (possibly her ideal to "make up"), etc... to "take advantage of the situation," just remember it's not about "what you deserve in return" but "what precedent you are setting in return."
In other words, you should
never change your own values or how you treat others. She is still a lady, likely a very screwed-up or selfish one, but still a lady. How you act will set the standard of how you either go forward with her or, in the case you will not accept her again, how she sees you. If you are understanding and respectful, yet still deny her while still treating her like a lady, she will only say extremely good things about you, possibly to her friends as well. That can lead to other opportunities with women, possibly her friends who liked you very much, but were "second" in getting to you.
It's all about
how you handle the situation, and the last thing you should ever do is "lash out" even if you will not be with her again.
With that all said, if my wife would have slept with another man on the night before my wedding, it would radically change my views of her. My wife and I have long agreed that we would contact each other before cheating, and at least tell each other what we were about to do -- even if that was just a phone call or voice-mail -- because we both deserved to be honest with each other before breaking that trust. If she didn't do that, then I could not trust her, and that's a huge portion of our marriage. If she did do that, and explained to me later why she did it and was responsible, yes, I probably would have still married her.
Why? I don't know about other women I could have been with, but I love my wife for her and I accept her values as my own. Because my chief priority is her happiness, and as long as there is a responsible way for her to enjoy life as she wants, I'd love her to accept it. Going the other way, I have no such desire to be with other women, and I'm not into that whole "fairness" or "reciprocation," even if she not only said I could, but said her fantasy was to see me make love to another woman. I can only focus on only my comfort with one woman, that's my value for myself.
But luckily my wife and I spent our evening kissing each other in a pool, at great duration with extensive embracing, in front of both sides of the wedding party. It kinda just happened as we met back with each other after our respective "parties." We found yourselves in the pool and unable to separate. I still have the same problem almost a dozen years later.
