We understand that you're going through a difficult time in your relationship due to communication issues, and we want you to know that you're not alone. Let's begin by addressing the silence issue, please be aware that communication is key to any relationship, especially to Christian believers. The Scripture tells us to "Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers. Let all bitterness, and wrath, and anger, and clamor, and evil speaking, be put away from you, with all malice" (Ephesians 4:29, 31 WEB). Knowing this, we encourage you to speak to this individual and let them know how you feel and what you need.
As we pray for restoration of communication and understanding in your relationship, it's important to ensure that this relationship aligns with biblical principles. If this relationship is a courtship, we pray that it will be centered on God and His will, with the ultimate goal of a godly marriage. If this relationship is outside of marriage, we lovingly remind you that God desires us to flee from sexual immorality, as it is a sin against our own bodies and against God (1 Corinthians 6:18-20 WEB).
Now, let's pray together:
"Dear Heavenly Father, we come before You today lifting up our brother/sister in Christ who is facing communication struggles in their relationship. We pray that You would restore open, honest, and gracious communication between them, that they may gain understanding and grow together in Your will. Lord, help them to listen actively to each other and to speak words that build up and encourage. We also pray that this relationship would be centered on You and Your principles, that it may bring glory and honor to Your name. If there is any sin present, convict and help them turn away from it. As it says in Matthew 6:14 WEB, forgive us our debts, as we also forgive our debtors. And if this relationship does not align with Your will, we ask that You give them the strength to let it go and wait for the spouse You have prepared for them.
Father, we also pray that [if they have not chosen to believe in Jesus Christ as their Lord and Savior, and be baptized in the name of the Father, Son, and Holy Ghost] they will believe in Jesus Christ, in His death and resurrection, so that they will have access to the Father and be saved. Remind them that it is written "whoever will call on the name of the Lord will be saved" (Romans 10:13 WEB). In Jesus' name, we pray. Amen."
In closing, if you are not praying in the name of Jesus remember there is no other name by which we may be saved. Acts 4:12 WEB says, "There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved."
