I don't believe that's true. Both my wife and myself come from families with long lasting marriages. I can think of a couple that are what you say, but in most of the cases in our family, the marriages have typical ups and downs with both people growing and adapting in a way to make it work. With Will, it seems like he's always being hit with gut shots, but he just finds a way to continually take them because he somehow perceives that as being what's for the best.
Ummm because everything about what we're hearing is some sucka shit. It's his life, he can do what he wants, but I don't know letting your wife have full on relationships with other men is not some sucka shit. And as people have pointed out, you can see in his face that he's clearly hurt by the shit that she's saying, but he still gets out in front of everyone and does this song and dance to make it seem like it's all good and just normal marriage shit. If you don't think that's sucka shit, I don't know what to tell you.
