We understand that you're feeling lost and heartbroken, Meewen, and we're here to pray with you and provide biblical guidance.
Firstly, let his remind you to whom you should pray. Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me. John 14:6 WEB
Firstly, know God's will for your life as His follower:
1 Thessalonians 4:3-5 WEB
For this is the will of God, your sanctification, that you abstain from sexual immorality, that each one of you know how to possess himself of his own vessel in sanctification and honor, not in the passion of lust, even as the Gentiles who don’t know God.
Wherefore be ye not unwise, but understanding what the will of the Lord is. Don't quickly rush into a intimate relationships, but understand God's will for your life.
And now abideth faith, hope, love, these three; and the greatest of these is love.
1 Corinthians 13:13 WEB
Colossians 3:12-14 WEB
Put on therefore, as God’s chosen ones, holy and beloved, a heart of compassion, kindness, lowliness, humility, and perseverance; bearing with one another, and forgiving each other, if any man has a complaint against any; even as Christ forgave you, so you also do. Above all these things, walk in love, which is the bond of perfection.
There are a number of areas that you need to be praying for and examining when you speak of Derrick.
You believe you gave him the wrong impression that you wanted a full relationship. You said you are not ready and neither is he.
He is in a divorce but no mention of a Biblical doctrine of divorce being met. If it is not for adultery or possibly his spouse has left him and is not willing to live with him this divorce should come to an end and he should be encouraged to oppose it.
Next while he is in this divorce episode you have already confessed your possible romantic feelings for him. He has already told you he sees you as an angel and a unicorn. Angels of God in the Bible are not described as having any romantic feelings. Unicorns go deep into myth and fantasy. While this sounds wonderful you need to examine your own motives. You need to see if you are confusing the strong emotional pain he has of a divorce for a need for help.
We are in still in a position of receiving the Bible's definition of adultery. Technically they are one until a divorce has happened and living with another man may be an act that may not be Biblically appropriate at this time. In Matthew 5:32 WEB But I tell you that whoever divorces his wife, except for sexual immorality, makes her an adulteress; and whoever marries her when she is divorced commits adultery.
Also observe Deuteronomy 24:1-4 WEB
When a man takes a wife and marries her, then it shall be, if she finds no favor in his eyes, because he has found some unseemly thing in her, that he shall write her a bill of divorce, put it in her hand, and send her out of his house. When she has departed out of his house, she may go and be another man's wife. If the latter husband hate her, and write her a bill of divorce, put it in her hand, and send her out of his house; or if the latter husband die, who took her to be his wife; her former husband who sent her away may not take her again to be his wife after that she is defiled; for that is abomination before Yahweh: and you shall not cause the land to sin, which Yahweh your God gives you for an inheritance.
You should pray for Derrick about the spirit of betrayal. The situation in which he sees you as an angel and a unicorn may be a symptom of the betrayal. This does not mean you are an angel or unicorn spirit but that you see their hearts fantasized through a cracked heart and pieces are laying all around.
He should also be prayed for about how quickly he can give up. He remains in unbelief that you committed a betrayal towards him which you deny.
As a relationship prayer that started as needing help from a non-Christian he may be the main need for 'the evil' to be removed.
1 Corinthians 6:14 - Don't be unequally yoked with unbelievers, for what fellowship have righteousness and iniquity? Or what communion has light with darkness?
We are not specifically told he is a Christian. For the husband who doesnt believe 1 Corinthians 7:14 WEB
For the unbelieving husband is sanctified in the wife, and the unbelieving wife is sanctified in the husband. Otherwise your children would be unclean, but now they are holy.
Even if the non-Christian testifies for Jesus Christ they are not sanctified in Christ. Consider this carefully before considering marriage.
You must pray for his truthfulness and check whether he gave an accurate situation of his divorce. Deuteronomy 19:18 tells us The judges shall make diligent inquisition; and, behold, if it be true, and the thing certain, that such abomination is wrought in Israel, then shalt thou bring forth that man or that woman, who hath done this evil thing, unto thy gates, even that man or that woman, and shalt stone them with stones, and they shall die.
Please remember to continually pray for God's will in this situation and note the relationship in the Bible whether from a father to a son or daughter or Christian brothers and sisters whose Father is God has the pattern of training, teaching, nurturing, and respecting each other.
Father, in Jesus' name. We come to You with heavy hearts, lifting up Meewen and Derrick. We pray for the evil to be removed from Derrick's life and for his heart to be mended and restored.
Father, restore the trust between Meewen and Derrick. Guide them both through this difficult time, and help them to seek You first in all their decisions. Surround Meewen with Your peace and comfort.
God if Derrick is not saved and has not believed in Jesus Christ please convict him that you love him and sent Jesus Christ to die on the cross for him and he can have eternal life if he believes in his heart and confess with his mouth that Jesus is Lord.
Lord, we pray for Your will to be done in Meewen's life and Derrick's life.
Father please convict us of things we need to repent from in Jesus name. We believe our prayer will be a sweet-smelling savor when we pray by the name of Jesus and we thank him for his sacrifice that brought us to you. In Jesus Name we pray. Amen.
