We understand that you've been waiting for a long time for this man to commit to marriage, and you're feeling worried and doubtful because he has blocked communication with you. Firstly, we want to assure you that God cares about your feelings and your future. However, we need to address a few things in your request.
Firstly, it's important to note that God speaks to us through His Word, the Bible, and not through audible messages. While He can guide our thoughts and impressions, we must always test these against Scripture. As you've mentioned that Jesus told you he is the man for you which does not align with biblical principles. If this is a real communication from God then it will be confirmed through the Bible. It is also possible that this voice is not from God. We can see that this could be a thought from a human heart or possibly a demonic spirit trying to mislead.
The Bible tells us, Trust in Yahweh with all your heart, and don't lean on your own understanding. In all your ways acknowledge him, and he will make your paths straight Proverbs 3:5-6 WEB.
It is possible that this man is not a Christian believer or does not seem to be pursuing a godly marriage with you. If this is the case, we encourage you to re-evaluate this relationship. The Bible tells us, Don't be unequally yoked with unbelievers, for what fellowship have righteousness and iniquity? Or what fellowship has light with darkness 2 Corinthians 6:14 WEB.
Regarding your doubt, it's important to remember that God's will is always good, acceptable and perfect Romans 12:2 WEB. If this man is truly intended to be your husband, God is able to soften his heart and bring him back to you. But if this man is not God's will, then God will either change your heart or bring a godly spouse. Never forget that God is in control.
The Bible says do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God Philippians 4:6 WEB.
Let us pray together:
Dear Heavenly Father,
We come before You, lifting up our sister in need of Your guidance and comfort. Lord, we ask that You speak clearly to her and to this man's heart. If this relationship is not Your will, we pray that You give her the strength to let go and trust in Your plan for her life. If it is Your will, we ask that You soften his heart and draw them both closer to You.
Help her to trust in You with all her heart, and lean not on her own understanding. Help her to acknowledge You in all her ways so that You can make her paths straight. Help her to obey the Bible WEB Proverbs 3:5-6. We pray this in Jesus name. Amen.
