Should women stay with unfaithful men?

Should women stay with unfaithful men? Arnold Schwarzenegger's wife Maria Shriver has left him after he revealed he fathered a child with a member of his household staff. Many people stay with their partners after they have been unfaithful. Journalist Jane E Allen writes about why many "wives of unfaithful high-powered men grin and bear the infidelities" while other women leave.
Malibu Cookie tweeted: "Women think "trice" before you "stand by your man" don't b so quick to defend him.
Rhoda posted on the LA Times blog: "Arnold had lots of affairs during his marriage, hidden with the support of Maria no doubt to armor their own children together."
And S Gayres posted: "Everyone is assuming that Maria did not know until now. You really believe she is blindsided by this at this time? There's a saying that says "a woman always knows". This was in the same house, C'mon."
