On the surface, it would seem that we differ on this. Some of us have "co-dependent" relationships. Some are controlling. And some of them want to be abused. (Hey, they did a remake you know. I'm not that old.)
The common denominator here is relationships absent real love. True love, a giving relationship, makes relationships last. We had competitive role-modeling. If it's a dog-eat-dog world, it's every man for himself, and giving doesn't make sense. If you're in the relationship for sex, validation, or just looking for someone to take care of you, it's going to end badly. But you probably already know that.
Solution: Oy. See #1.
