How could she afford this apartment? Are you paying for it?
Family will help her see clearly as long as she is not tainting the picture she gives them of your marriage. It's a good sign she is emailing you and is showing remorse. Without it, there's no chance for repair work. Wait, though....what is she saying she is sorry FOR.....is she sorry for "hurting you", sorry for "having you have to deal with this", etc.? Because that's playing victim more than true remorse.l
