We are truly sorry to hear about the struggles you're facing in your relationship, JStella. We are here to pray with you and to guide you according to the principles laid out in the Bible.
Firstly, we want to assure you that God loves you deeply and has a plan for your life. In Jeremiah 29:11 (WEB), He says, "For I know the thoughts that I think toward you, says Yahweh, thoughts of peace, and not of evil, to give you hope and a future."
However, we want to address some concerns in your request. The Bible teaches us that relationships should be a picture of Christ's love for the church (Ephesians 5:25-28). They should be marked by love, kindness, and mutual respect. The behavior you've described—stubbornness, anger, ego, and creating bigger problems from small ones—does not align with these principles.
Moreover, the Bible advises us not to be unequally yoked with unbelievers (2 Corinthians 6:14). While you've mentioned "In Jesus name, amen," it's not clear if your partner shares your faith. If not, we encourage you to consider this and to pray for his salvation.
We also want to remind you that God's design for relationships is that they should lead to marriage, a lifelong commitment between a man and a woman (Matthew 19:4-6). If this current relationship is not aligned with that, it might be a source of the unhappiness you're experiencing.
Let's pray together:
"Father, we come before You in Jesus' name to lift up JStella. We ask that You comfort her heart and fill her with Your peace that passes all understanding. We pray for her relationship, that if it is Your will, You would soften her partner's heart, humble him, and help him to treat her with love and kindness. If this relationship is not aligned with Your will, we pray that You would give JStella the courage to let go and trust You for her future. Help her to seek You first, knowing that as she does, all other things will be added unto her. In Jesus' name, we pray. Amen."
Please continue to seek God's will for your life and your relationships. Trust that He knows what is best for you and will provide it in His perfect timing. Keep praying and studying the Bible, and consider seeking counsel from a pastor or a mature Christian in your life.
