Not meaning anything but my sincere impression of Crazy's marriage. I have a feeling that they both have cozy friends of the opposite sex. That's why neither of them are too bent out of shape about such friendships.
Being the Devils Advocate:
Crazy is not the first person in the world to become emotionally entangled with another woman and If she has her little crush same thing for women, not the only one in the world.
That scenerio does not necessarily mean that either of them will act on their attraction nor does it mean that it will cause them to break up. Some people appreciate what they have at home and don't distract from that something just because they are crushing on someone else. It's called taking care of your priorities.
Contrary to popular belief. He doesn't NEED to do anything just because that's what we'd do. Some people can manage to keep it all together without driving a wedge between the emotional connection with their SIGNIFICANT other.
In any event... time will tell what does or doesn't happen to his marriage.. In the meantime; you can lead a horse to water but you can't make him drink.
“The willingness to accept responsibility for one’s own life is the source from which self-respect springs.” ~Joan Didion
