It's up to the individual whether they want to DB, or stand or not.
I am NEVER going to challenge someone to move on. I will ask folks who are being abused to seek help immediately...and to leave if they are in danger.
I do challenge those who recommend that someone move on. This is the site for hope. It is our job to put the marriage first. You don't know what the person is able to do. Even if you think you know. The rest of the world around them will be telling them to move on. This is likely the only place they come where they hear ideas about saving their marriage. Unless THEY SAY and show ACTION they have decided to quit, OUR JOB is to BRAINSTORM SOLUTIONS for them.
Many folks leave or kick their spouses out and a year or two later regret it and wished they had tried longer or just stood.
