All people are flawed. That is not meant to be a shocking statement, just a statement of truth.
Because all people are flawed, that means we have attractions to flawed people. We maintain our relationships with these people who have issues, some more serious than others, that may bother us. That is the nature of living in a world full of humans. The issue comes from the reason you stay attached to a person with flaws that should deflect you.
The two terms that get confused in this mess is ‘because of’ and ‘despite.’ People who stick by you ‘because of’ are in need of flawed people to make themselves feel more empowered and less flawed. People who stick with you ‘despite’ are looking past whatever flaws are there, and just like being with the person.
It might seem like the wrong semantic, but make note of why your friends are your friends. Do they need to be around people that make them look better by comparison? Or ones that truly enjoy your company, even if some of your quirks are off kilter?
