people

People are needy.
...and I'm at the top of the list. 

When we try to get our needs met by another person or expect them to complete us, we are setting ourselves up to be hurt and disappointed. For a time, it may feel that the other person is fulfilling you. Maybe they are temporarily meeting needs in you that you don't even realize exist. Having this person in your life makes you feel better. 
Chances are they may be looking for you to fill holes in them too. It's a far cry from an antidote that will heal us.

The reality is we are all flawed and incapable of completing someone.
We are imperfect humans, so when we place expectations on people to fill us, it's just a matter of time before they fail us or we fail them. Pain, hurt and disillusionment are inevitable. 

This all sounds very negative, but it's the truth. I've lived long enough to experience it. 
We all have God given needs and desires inside of us that only He can completely satisfy. All of our searching and grasping is futile. He has been there all the time just waiting for us to ask him to be our soul-mate, to fulfill us. And he does it so perfectly, erasing our neediness towards others. I'm finally feeling what's it like to be made whole by my Maker.
I've stopped expecting people to fulfill me and let my Maker do that instead, I have more peace and security than ever. I am more accepting and forgiving of myself and others.

Healthy individuals give others the space to fail and the opportunity to learn from their mistakes, removing the pressure of unrealistic expectations.  You are healing instead of hindering. And your relationship takes on a new freedom giving space for pure love.
It allows the Father's gracious love to flow from you into them.

From 1 John:

"We know how much God loves us, and we have put our trust in his love.
We love each other because he loved us first."
