I doubt that that is the case. There haven't been any hints of settled Sam who has stopped hunting, just of Sam with a relationship. (Maybe I am too hopeful in thinking that the writers don't necessarily equate being in a relationship with "normal" settled life, but I don't really think his situation is meant to be parallel to Dean's with Lisa.)
