When Do MLC-LBS Officially Give Up?

[ForGump]

When do people left behind by MLC spouses give up? I'm sure it varies from person to person, and situation to situation. But is there any discernible pattern? Is there some milestone event after which LBS's give up, typically? Do LBS's tend to hang in there as long as they remain married, but give up when the MLC-er divorces them? Or do most LBS's hang in there long past the divorce?

I know, I know... you DB for yourself, and you DB forever for life but ... there's got to be a point at which you abandon all hope, and just stop caring.
