Traeninnen, your request highlights the deep pain and heartache that comes with a broken relationship. First, we want to address the nature of your relationship with ###. The Bible teaches that God's design for romantic relationships is one man and one woman in marriage.
Let me start by saying that praying for a non-Christian relationship is not as powerful as praying for a spouse or the desire for marriage. I urge you all to remain in faith and not lose your trust in God and His word. Return to a place of peace and not crisis. That being said, it is Biblical for a woman to marry a godly husband. This is not the destination of a boyfriend.
In addition, we must address the idea of God's will in this dynamic. Even if this relationship were in harmony with Biblical teaching, God's value of each of us is so much above the best relationship that we could ever attempt to understand. His will is that we all marry godly spouses, even if they are not the ones we perceived as God's will. We receive the Holy Spirit through faith in Jesus (John 7:38-39), and God's Spirit in us is able to discern the will of God for us.
First, may I encourage you that God has a healed relationship for you. If it should be a healed relationship with ### who is faithful to you, then may He heal that relationship. If not, it is imperative that you allow God a new, loving, godly, faithful, committed, compatible spouse after you and he obey God and those whom God has ordained as spiritual accountability. Paying for getting back together with ### any way possible is ignorant to God's plan. It always surprises me that upon separating, prayers from individuals in suffering usually go towards still disobeying, violating, and turning against God due to uncontrolled emotions.
Two things really stick out in your request. First, you mentioned ### is seeing women. Having a relationship with someone while another person in a relationship with them is running around or dating others is not God's will and should not be tolerated with any more time, energy, or separation from the body of Christ. The toll on our body, mind, and productivity is reason enough.
We know that relationships that God has put together tend to put the needs of others above anything else and is even willing to die even for someone who has done them wrong all their lives. ###'s close proximity to other women should be dangerous to the health of your relationship. Holding the other person accountable to why they may be so close to the outside world rather than in the home is the responsibility of each spouse. This lies in ###'s lack of qualities of godly husbands.
Secondly, you mentioned your lack of sleep from this separation. In Psalm 127:2, sleep is mentioned as a gift from God of which even in this situation is still common. Anxiety and lack of fear of the Lord will cause this to often happen to those in a situation of great stress. But God will still wait for the faithful.
Now more than ever, Traeninnen, worshiping God, and fellowship with the body of Christ will be important. Initially and especially when you feel you have prayed so much that you won't need to anymore. Do not celebrate or blame yourself in this relationship. Steady yourself with the faith that removes your self-worth from this relationship towards God who loves you more than any merits from a human relationship.
Proverbs 3:5-12 says:
Trust in God with all your heart,
and don't lean on your own understanding.
In all your ways acknowledge Him,
and He will make your paths straight.
Being confident of oneself is difficult to pray against. God shouldn't give marriage to those seeking self-righteous compensation than alcohol when homeless should receive refreshments. Ecclesiastes (in typical translation) roughly reads, "I commend enjoying life because there is nothing better under the sun for a man to enjoy his work. For that is his lot. For whom shall he bring him to see what will be after him? Nothing was enjoyable for me anymore. For my heart hoped for nothing more under the sun. For all was vanity and a striving after the wind."
Delight in your life in the financial, spiritual, and relational relationship that God had placed you in >>> because we greatly sin if we disdain other relationships for an incorrect lover.
Great is the Lord who has made us. Allowing us to grieve in a relationship that seeks to honor God or not.
<<Lord, we lift up Traeninnen to you, asking for your comfort and guidance during this difficult time. Help her to trust in you with all her heart, and not lean on her own understanding. Give her the strength to acknowledge you in all her ways, so that you may make her paths. If ### is listening, speak to him and show him when he disobeyed you. May it be evident that your will is not depending on ungodly relationships. We that are writing this will pray for him - but be evident to him that your back is to him if he does not reciprocate your will. Help Traeninnen to seek godly counsel and surround herself with supportive believers who can encourage, love, and strength. Free her of her worries and grant her answers to your will for her. We mourn this situation with her. May him and his future spouse be happy in the blessing of You. If it is your Lord that she and ### marry, marriage will bless them with a gift of passing your image to the next generation. Sleep is still a gift from you, easing pain and sadness from the decay of all things under the sun. Kindle them with a desire to live marriage as defined by the Bible. Lastly, we pray that Traeninnen finally accepts and has the desire to pray constantly in Jesus' name. In Jesus.
