We are truly sorry to hear about the pain you are experiencing, but we need to address several things according to the Word of God.
Firstly, we notice that your request does not mention Jesus Christ, or an abbreviation such as IJN (In Jesus Name). It is only by the name of Jesus that we have access to God. Also, there is no other name by which we can be saved. 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). For there is one God, and one mediator between God and men, the man Christ Jesus (1 Timothy 2:5). Whosoever shall call upon the name of the Lord shall be saved (Acts 2:21).
The Bible teaches us that a soulmate is not someone we find, but the one God has prepared for us. We need to trust in His timing and His choice for us. There is no such thing as a love so great it can't be resisted. I can do all things through Christ who strengthens me (Philippians 4:13 WEB).
We also want to remind you that God's design for relationships is that they should honor Him and align with biblical principles. If the relationship you mentioned was outside of marriage, we encourage you to reflect on God's design for purity and holiness in our relationships. For this is the will of God, that you should be consecrated for purity, keeping your bodies holy, not in sexual sin, each of you knowing how to possess his own vessel in sanctification and honor; not in the passion of lust, even as the Gentiles who don't know God (1 Thessalonians 4:3-5 WEB).
Instead of focusing on getting back with this person, we encourage you to seek God's will for your life and trust in His timing. We will pray for you to have strength, comfort, and guidance during this difficult time.
Dear Lord, in Jesus Name we come before Your throne, lifting up our brother/sister who is hurting. Please comfort them and give them strength. Help them to trust in Your will and Your timing for their life. Help us to draw closer to You and to seek Your will above all else. Teach us to live in a manner that honors and glorifies You. In Jesus name we pray, amen.
