A lot of excellent advice above but I confess that I’m approaching this issue based solely on your original post at the head of this thread.
IMHO the real issue is your wife.
In an ideal world your brother would make amends and you two could find a way for you all to be a family-unit. But even in a less-than-ideal world chances are you and your brother (OM) could be at the same Thanksgiving table without too much awkwardness and hate. Maybe even talk about the game or whatever. In an even less less-than-ideal world you could have a good relationship with your sisters without ever again talking to your brother. In an even less less than-ideal-world you could live a good, productive life with minimal interaction with any of your siblings, or interaction completely on your terms.
But… in no world that I know of can you have a good marriage if your wife sees you as the lesser of two options…
I don’t see a marriage where you have the same options to demote your wife the way you could your brother. You can put distance between yourself and your brother, remove him from your contacts, refuse his calls… whatever. But that would never work in a marriage.
I think the key issue might be to a) make your wife fully understand the consequences of her "slip-up" and that if what she’s saying about always having preferred your brother over you then she is fully free to go be with him, and b) you both commit to the marraige or commit to ending it.
I have this theory. I think that often people hang on to some excuse to remain where they are, even if they think the grass might be greener somewhere else. When their excuses are peeled away – removed – they become reluctant to go to where they always insisted the grass was greener because they realize they have it pretty good where they are.
I have another theory that is connected to the above issue: People tend to justify their actions – even when they realize they aren’t logical, sensible or even sane. The embezzler will insist it was only a loan and they intended to pay it back, the rapist that the woman wanted it rough, the speedster that he was just following traffic…
I think that your wife’s "excuse" and pining for the OM as in putting you in second place could be a combination of the two.
I think it could do you a lot of good if you were to really think long and hard about what you want in your marriage. Having been married myself for several years I realize the original passion and all that might not be there, but I would assume that a key-requirement is that you believe your spouse wants to be with you and doesn’t pine for someone else. You might have it – but does SHE have it?
Then take the concept of "love" – something I believe in. If you love your wife, would you want to keep her even if it wasn’t mutual love? If you were holding her back from her "true" love?
Then take all this and give yourself a few minutes to think how your life would be impacted if you two were no longer married. Be realistic: You won’t starve, you won’t be sleeping in a box, you won’t automatically become a hermit. In some ways I’m challenging you to do what I am later going to suggest you do towards your wife: Remove all excuses for getting out of the impasse I sense you are in.
Then – if you reach the conclusion I hope you reach – peel away all your wife’s excuses for why she remains married to you despite you being a compromise. Allow her the freedom to go be with your brother. Heck – give her your blessing to seek happiness! Refuse to be a compromise.
I have a feeling that once you peel away the layers… once she has the "freedom" she seeks… she can find the real reasons she went this path, and those reasons won’t be because you are lacking or that she desired the OM because he was so much better than you in any way or form.
I think this can be the basis to either rebuild the marriage from or rebuild your life IF your wife is true in her explanations in why this took place.
Are you by any chance the youngest? Or is the OM the youngest? As the youngest of five siblings, it took quite some time for the others to realize I was a man and had my own voice. I guess I was about 35-40, and I know my sisters had a hard time with it. Part of growing up, part of marriage and all that is that you move away from what was your family to the phase where you build YOUR family. That period can cause pain, but IMHO its imperative. You are allowed to decide on what premises/conditions you interact with your grown-up siblings and their families.
