I think we all have things we need from other people: friendship, respect, trust, love... How we approach getting those needs met, and as Suzie12 points out, who we look to to have those needs met, make a big difference in whether the needs are healthy or not.
Example: Continuing to expect abusive STXAH to respect and love me was incredibly unhealthy for me. Looking to my sisters, brother, mom and dad for respect and love is healthy.
