What is an unhealthy relationship vs. a healthy relationship?

“Impurity and a phony fellowship (a relationship that is fake) enslave and it imprisons whereas freedom is genuine fellowship with The Father through what Jesus demonstrated on The Cross and He sends us His helper The Holy Spirit.” - G.S.Notes

This is a good quote I found reaserching this topic: (fake friends hate honesty) “Fake friends are like shadows: they follow you in the sun but leave you in the dark.”
