JS,

Here's a way to simplify this. Marriage really screws up your perspective on the type of SH#T people will tolerate.

Say you were single, in college or after. You met a hot chick, but every time you went out, you found out she was also dating the basketball team. It would kind of kill it, no? You'd just move on.

But you're married. So suddenly, you give her a pass on it. It's only a friggin EA, right? Couldn't be a PA, she told me so!

The fact that she's clinging so hard to this "EA" implies that it's pretty powerful to her. So be it. Let her have this EA, let her know that she's choosing a friendship over her husband.
