I wanted to ask other Christians if this is the right thing to pray for. There is a friend who I love very much who walked in and out of my life years ago. While even though I have had a multitude of friends and relationships God has blessed me with in said time, my life has not felt complete without her. I've always had this nagging feeling in my heart of wanting her in my life. When she left years ago, I moved on and forgot about it, but the feeling kept coming back even when I wasn't directly thinking about her.
I want to pray to the Lord to ask that he return her to my life, and give me peace, and also ask other Christians if this is the right thing to pray for (I fear of praying for the wrong things), and to pray with me.
Dear Jesus, please return this loved one to my life, if it is of your will. She is of great importance to me. I ask for peace and understanding during this time. Amen.

Lord have your perfect will be done in this person's life and their situation. Give them wisdom from above to do what's right in your eyes, and best for him and that other person. I pray this in Jesus name, amen.

Lord please guide this man to the correct descision and help him find Peace, in Jesus Name, Amen

Lord Jesus. I pray that you work your will in this man's life and the life of this woman. I do believe that you can place people on our hearts and will bring us back together when the time is right. I pray that you will guide this man and this woman and that your perfect will be done. May YOU be at the centre of this relationship going forward and may the relationship (if it is supposed to be) be to your glory. In the name of Christ. AMEN.
