Instead of putting a human down for not meeting a need that you expected them to meet, take it to the Father from whom your help cometh. When applicable, He uses people of His choosing and not your own. God uses these experiences to show you that He is your source and to also help you to not operate in idolatry.
I have been on both sides of this coin and neither side feels good. In disappointment, learn how to seek God first and foremost and to see them as God sees them. In failing to meet a need, a person learns humility and increases in their strength against people opinions.
Manage your expectations for other human beings and watch yourself obtain a freedom that cannot be compared. Manage your expectations and watch your vision of the roles of other people in your life become healthier. Be blessed on purpose!!
