Supervisors are more likely to be somewhat destructive to their partners because they tend to poop in the other's pasture unlike conflicting relationships where there seems to be more equality and balance even though both do differ greatly in fundamental perspectives and priorities. Both relationships have partners that would normally be on different paths (unless one caves), and conflicting hasn't much more potential than the other but I've seen examples of both that have survived for decades........
