Your prayer shares a deep and honest ache, a long loneliness and the pain of a marriage where you did not feel loved or valued. God sees that hurt and hears that cry, and He cares for those who feel alone and cast aside.
I want to gently help you with the idea of a twin flame, because Scripture does not teach that God has made one mystical counterpart for you to find. What Scripture does teach is that in the beginning God made us male and female and designed marriage to be a lifelong covenant where husband and wife complement one another and become one flesh. That was His perfect intent from the start. Because human hearts are hard, the law later allowed for divorce, and Jesus pointed back to that original intent while acknowledging that hardness.
For those who have been married, God's word gives clear and careful instruction. The wife is bound to her husband as long as he lives. If a separation has taken place, the instruction is to remain unmarried or to be reconciled. Only if a husband has died is a woman at liberty to marry again, and then only in the Lord, that is, to a fellow believer who walks with Christ. This is not to burden you, but to protect you from pursuing a new relationship in a way that would not be pleasing to God. The teaching also says that the unmarried person is able to care for the things of the Lord, to be holy in body and spirit and to serve Him without the divided concerns that marriage brings, while the married person must care how to please a spouse. Singleness, though it can feel lonely, can be a gift in which you have unusual freedom to draw near to the Lord.
Marriage itself has a simple pattern in Scripture. The wife is called to come alongside her husband as unto the Lord, and the husband is called to love his wife as Christ loved the church and gave Himself for it. When those callings are kept, marriage reflects Christ's love. When they are broken, pain multiplies, which is what you experienced. Neither husband nor wife is complete in themselves, but our deepest completeness is not found in finding another person who will finally make us whole. It is found in Christ Himself.
Living together or sexual intimacy outside the covenant of marriage, and seeking a spiritual partnership defined by ideas like twin flames, does not lead toward holiness or healing. There is no biblical justification for shaping our love lives around those ideas, and following them will only deepen loneliness.
In this season, the most healing path is to bring your loneliness directly to Jesus, who suffered for us, the just for the unjust, to bring us to God. Ask Him to heal the wounds left by your former marriage, to fill the empty place with His presence, and to make you holy and whole in Him. If God in His providence should bring marriage again in the future, it must be according to His word, in His time, and only in the Lord. Until then, you can use this time to seek Him fully, grow in His word, fellowship with other believers, and serve Him with an undivided heart. Scripture says that those who abide as they are, content in the Lord, can be truly blessed.
I pray that the Lord will comfort your heart, lift the weight of long loneliness, heal you from the hurt of not being cherished, and draw you into a deeper experience of His love that never fails. I pray He will give you wisdom, purity, and contentment as you walk with Him, and that you will know how tenderly He watches over you and provides for you day by day.
