WAT's Quick Start Guidelines for Betrayed Spouses
Rule 1: Don't try to make sense out of what's happening. You are not dealing with rational people, so your normal thought processes won't work. This is exactly why you're confused. Your spouse will act as if he/she has been abducted by aliens and had their brains scrambled. Just watch and don't take any of this personally. If you can do it calmly, confront your spouse with any solid evidence you have of the affair, but expect denials and lies beyond belief.
Rule 2: Don't be in a hurry. There is little, if anything, you can directly do to separate the affairees. They have to do this on their own. The affair will end. To hasten it's end, do not interfere with it. The fact is that there may be almost nothing you can do right now to make it better but there is a WHOLE LOT you can do to make it worse. On the other hand, there is a LOT you can do indirectly to compel the affairees to end the affair on their own. Read this post and all its responses: On revealing the affair to the light of day
Rule 3: All snooping is good and necessary - but be ready for an ANGRY reaction if your snooping is detected. Refer to Rule 1. Think NOT of snooping as disrespectful spying, but as necessary affair research. If caught, you will be accused of "invading my privacy!" Respond, "No, I was revealing your secrecy." In some cases, contacting the OP may be beneficial, but in other cases, a disaster. Read this post and all it's responses: On contacting the OP
Rule 4: Don't beat yourself up for "causing" the affair. You are partly responsible for creating the environment which made the affair possible, and you need to examine yourself critically to see what changes you need to make, but you are NOT responsible for your spouse's decision to have an affair. Nonetheless, your wayward spouse will likely accuse you of all sorts of misdeeds, rewrite your marital history exaggerating trivial issues, and shift blame to you in their attempt to lessen their guilt and justify their decisions. In affairs, culprits abound except in the mirror.
Rule 5: This will likely be the worst experience of your life. You are a prime candidate for depression, so see a doctor if you feel like you're having difficulty coping. You may need anti-depressants. You are also a prime candidate for your own affair. DON'T DO IT!
Rule 6: Do not recruit your spouse's family in an attempt to "help." If they ask questions, answer honestly, but in the long run, do not expect their support - if you get it anyway, consider it a bonus. Blood IS thicker than mud.

Rule 7: Do not expect too much right away from the wayward spouse even if they have already ended the affair. It may feel like you are they only one who is trying to save the marriage. You are not a doormat, just a loving, faithful spouse.
Rule 8: You will be told by well intending "advisors" to "Throw him/her out!!!" or, "Say good bye and don't look back!!" Instead of following this advice, learn everything you can from books, websites like this one, and counselors about the ways to find the silver lining in this cloud. Seek advice as soon as possible.
Rule 9: In ongoing affairs, if your spouse's OP is also married, consider informing the OP's spouse if you know their identity. The purpose for this is to reveal the affair on the other side which may motivate the OP to end it. This should not be done without guidance.

Rule 10: Your situation is not likely to be unique. The actions and statements of affairees are surprisingly similar. You can gain understanding and support from just about anybody else who has experienced an affair.
