GH is right -- you have to make decisions for yourself. For me, kicking my W out was ultimately the right decision. GH, on the other hand, has made fantastic progress by simply being patient and doing basic DB techniques such as GAL and "as if".
As for making things too comfortable, I can tell you that "punishing" your W will not help. If you want to make a decision to make your own life easier, then go for it ... but you can't change her, because she can only do that for herself.
The LORD is near to all who call on him, to all who call on him in truth." (Psalm 145:18)
