A relationship should be based on mutual trust. Control is a way of compensating for lack of trust/security. I'm a guy, and if a girl was trying to control me, I would run, not walk, away from the relationship, but I would also expect her to do the same if I was trying to control her.
But thats just me. Your situation describes a girl dependent on the control of others... I dunno what happened to her in the past, but it sounds like she's having trouble coping with independence. Or is just wacked in the head.
