I agree with Mounty,
I tried and lost myself trying to save a guy I liked alot.
I was using up all my energy preaching, loving , trying to be an example to him.
I cared and he didnt.
You have to let go
Right now he's not the one, and only God could make him the one.
So step aside keep him in pray,and let God be God.
Give all your emotions to God,
I know its hard and you feel like your abandoning him, but you can not be his saviour.
Right now release yourself from all attachments and seek God.
So your emotional healing can start now.
Heavenly Father, I ask that you bless this guy, remove the blind folds , soften his heart and heal him from all emotional pain and distractions. You know his heart, so let your will be done.
Lord I bring my sister to you give her guidance and strength to move forward. Release her from all feelings and fill her with your love. Create in her a clean heart, bless her thoughts, her steps and everything she does. I come against anxiety and depression in the name of Jesus.
Give her peace.
Amen
