Things that make you go hmmm

I have a friend who is getting divorced for the same reason I am. Yes, it's true, her husband cheated on her, too. What I don't understand, besides the obvious - why do husbands cheat, is why she is so nice to him. I can't figure out if I am reading too much into this, if I am mean, or if she just isn't ready to let go yet. Tonight she calls me by accident, she meant to call our friend Lori. She wants to ask Lori to watch her kids for a little while because she doesn't want to leave her husband alone. I replied with "WHAT??!!" So she proceeds to tell me that the woman her husband cheated with is in the back of a police car headed to jail. I ask if her husband is OK. She said yes but no. Then she explains that the woman's husband cut himself, pretended that she attacked him and called the police. Her husband is so distraught that she is cancelling her plans, going home to take the kids to her friends, and is then going to comfort her husband because she doesn't think he should be alone. This is a true story. You might have to go back and read it again.
