You want to know what I told him? "Congratulations, man, I'm happy for you." He is very happy with her, and that is more important than any judgment that I could cast at him. Judgment and friendship don't go together.
But isn't that the question. If you are not happy with your life, and you see someone who is happy in a relationship, then subconciously, people want to see that relationship fail.
The problem with the OP is that he just got burned with his ex-wife going with another guy in the same place he works at and they are planning to marry. So his experience he is subconciously trying to get back at his ex-wife by breaking up the relationship his friend has because he sees his ex-wife in the woman his friend is planning to marry and if he breaks it up, then he has one-up on his ex-wife in some way.
Suppose the marriage actually does work out and they both live happily ever after? It could be they are soul-mates that are meant to be together and the previous marriage was simply a mistake. Maybe they got married too yonge, or you know, as time goes on people change. The person you marry is never the same person you divorce.
Why would the OP be so invested if it wasn't to get back at his ex-wife seeing he can not break-up the relationship with his co-worker and his ex-wife, but if he can break-up the reationship with his friend then he has a small victory.
So, even if the advice is correct, you still have to see if there are other subconcious processes that are going on. The best appeal to someone on these matters is always a religious conviction, because apart from that, then people want love. If they don't experience it from God, then they want it from a woman, and if a woman is showing a guy real love and taking him on, and there is something special going on, then why be the kill-joy? Nobody can judge if a relationship will succeed or fail down the road.
A friend is someone who is there for a person, even if they know they will make a bad choice. In Bible_Belt's case, they ALREADY married, so he'll just be a kill-joy at this point. I wonder what he would have said BEFORE they got engaged if he came for him for advice.
