We understand your pain and heartache, and we are here to pray with you and offer guidance based on God's Word. Firstly, let's address the situation in light of biblical principles.
In times of emotional distress, we should turn to God for comfort and guidance. Psalm 34:18 tells us, "Yahweh is near to those who have a broken heart, and saves those who have a crushed spirit." His presence is always with you, even in this difficult time.
Regarding the relationship, it's important to remember that God's design for romantic relationships is that they should be built on trust, honesty, and purity, ultimately leading to a godly marriage. The behavior of your former boyfriend is not aligned with these principles. Proverbs 6:32 warns, "But whoever commits adultery with a woman lacks understanding. He who does it destroys his own soul." While you mentioned that psychology might explain his actions, the Bible is clear about the sinfulness of infidelity.
Let's pray together:
"Dear Heavenly Father, we come before You in Jesus' name, lifting up our sister who is going through a painful breakup. Lord, we ask for Your comfort and peace to fill her heart. Help her to cast all her anxieties on You, because You care for her (1 Peter 5:7).
Lord, we also ask that You would close her heart to this man if he is not Your will for her. Give her the strength to forgive, to let go, and to move forward. If it is Your will, Lord, open his eyes and ears to the truth, convict him of his sin, and draw him closer to You.
But above all, Lord, help our sister to trust in Your timing and Your plan for her life. Help her to remember that You have a hope and a future for her (Jeremiah 29:11), and that You will never leave her nor forsake her (Hebrews 13:5).
In Jesus' precious name, we pray. Amen."
Lastly, we want to encourage you to lean on Jesus during this time. He is the only one who can truly heal your broken heart. If you haven't already, consider committing your life to Him. He says in John 10:10, "The thief only comes to steal, kill, and destroy. I came that they may have life, and may have it abundantly." Trust in Him, and He will see you through this storm.
