So, rockbottom,
What are you going to do about all of this?
Recovery is a rough thing -- the fantasy a WS spews ("I felt left out") is sometimes easier for the BS to accept than digging for the real root of the affair.
The "circumstances" around affairs may change, but when you strip all that away, most affairs are really the same underneath.
Fortunately, as I think most MB's with recovered marriages will attest, the process of recovery is really the same underneath as well. Sure, circumstances will vary -- what emotional needs have to be met, how long it takes, what kinds of counseling, etc. But the MB principles are the foundation for recovery.
I've read some of your posts (but not all, sorry) so I believe you're still in Plan A, right?
How is that coming? Has your wife shown remorse?
I guess I should have seen the red flag when my friend had his affair about 5 years after he and his W (my former OW) had supposedly worked it out.
Is this couple still "friends" of you and your wife? If so and you have contact with them, I can see a bit where your wife may feel a bit of discomfort whenever you are together. Continually seeing your OW could certainly have contributed to her keeping resentment and unresolved issues alive all these years. I can't imagine being "friends" with any of my wife's OM or their wives. I hope this isn't the case for you.
Anyway, I guess I shouldn't have called two of them EA. Basically I see it as 2 people using each other. They were instances when these guys flirted with her and it turned into perverted emails, swapping perverted pictures and stuff. I guess it wasn't emotional. Just sick stuff.
I believe they were Emotional Affairs -- I just disagreed with you characterizing them as having no emotional involvement. Your wife may not have "felt" anything for the particular creep sending her the pictures/email/etc, but she definitely was getting emotional needs met by this. As you say, the attention fed her self-esteem, and she was getting emotional needs that should be met by her husband met by some other man. That's an emotional affair. The fact that she was a willing participant is betrayal.
The simple rule that usually works (not always) is that if your wife is doing something with another man that she doesn't want you to know about and would hide from you, then it's an affair, or at least the prelude to an affair.
Keep strong, rockbottom -- it's a lot of work and you both have a lot of history to recover. You can do it. You have shown yourself committed to recovering your marriage. She will emerge from the fog and see you for the dedicated husband you are if you stick to Plan A and recovery.
