I think that the definition of a bad marriage is different for everyone. Some women are not traumatized by infidelity...heck...they go for it, too! The same with alcholism...it's not a breaker for everyone. For one woman it might be that her husband who was faithful and sober but was totally unattentive and never listened to her...made her terribly lonely and unhappy.

I think we can only answer the question for ourselves in the context of the relationship that we are in.

And I guess for the me answer to how long she stays in what she considers to be a bad marriage depends a lot on her since of self worth. It's only when you decide that your personal life is more important than anyone else's opinion that you can actually leave.

Just my thoughts.
