We understand that you're going through a difficult time, but we want to help you align your desires with biblical principles. Firstly, it's important to note that the request focuses on an ex rather than a spouse, the goal for a relationship for a Christian should be marriage, not having a boyfriend or girlfriend for the sake of it. While it's natural to feel hurt and want reconciliation, the most important thing is to seek God's will in this situation and His will is for you to be equally yoked in marriage with another Christian rather than to chase after someone who has rejected you. We need to pray for God to guide you both and for you to have strength and for her to have a desire to be married to a Christian.
In 2 Corinthians 6:14 WEB it says Do not be unequally yoked with unbelievers, for what fellowship have righteousness and iniquity? Or what fellowship has light with darkness? If she is not a Christian, pursuing a relationship may pull you away from your faith. It's crucial to consider whether she shares your faith and values.
Moreover, it's clear that the relationship encountered problems, and she chose to break up. It's important to respect her decision and use this time to seek God's face and His desire for you to be married to a Christian and to seek Him first. Trust in the Lord with all your heart, and do not lean on your own understanding. In all your ways acknowledge him, and he will make straight your paths in Proverbs 3:5-6 WEB.
Instead of focusing on contact from your ex, let's pray for God's will to be done in both of your lives and for you to have a marriage that is honoring to God. Let's also pray for your healing and peace during this time. We also hope that you will examine your relationship with Jesus Christ. It is by His name that we can approach God. We want to encourage you to seek first the Kingdom of God and His righteousness, and all these things will be added to you as well.
