We are truly saddened to hear about the struggles you've faced and the pain you've endured. First, we want to remind you that it is only by the name of Jesus that we have access to God. The Bible tells us, For there is one God, and one mediator between God and men, the man Christ Jesus. All power and authority is his. Let's address the issues and turn to God in prayer.
We must first address that God's will is for you to have fulfilling loving relationships. You are correct that God does not want you to be unloved or unhappy. God's will for you is to be fulfilled in love, but it is important to clarify what love is and God's design for it. God is love and God's love is real and true. God made mankind to be loved and to have a loving relationship with Him through Jesus Christ. God also made marriage and it is a lifelong commitment between a man and a woman. Biblical marriage is honorable and the relationship between a man and a woman should be treated as sacred. Sexual intimacy is to be reserved for marriage. Proper relationships should be based on biblical courtship where the goal of having a boyfriend, as you mention in your post, should be looking for a Christian spouse.
Marriage is honorable in all, and the bed undefiled, but God will judge sexually immoral people and adulterers. It must be noted that a lot of the problems in this world stem from not honoring God. Fornication and adultery are sins and the Bible warns us that we should not be involved in such things.
When you mention your father's words, it's important to understand that a person's words only have as much power as we allow them to have over us. It is not biblical to believe in curses from another person. No one has power to cause someone to have a loveless existence. The real power is the power of Satan who wishes to deceive and destroy. This is why we must pray to God to break any power that the devil has over your relationships. Greater is He who is in you than he who is in the world. If you have not accepted Jesus Christ as your Savior, repent and do so now. For God so loved the world, that he gave his one and only Son, that whoever believes in him should not perish, but have eternal life.
We understand you desire a loving relationship, but we encourage you to pursue God with all your heart. Delight yourself in the Lord and He will give you the desires of your heart. 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. Surrender your desires to God and He will bless you with His plans for your life.
Let's pray together:
Dear Heavenly Father,
We come before you in Jesus' name, lifting up our sister in need of your divine intervention. We pray against any spiritual oppression or bondage that may have resulted from words spoken against her. We declare that no weapon that is formed against you shall prosper, and every tongue that shall rise against you in judgment you shall condemn.
Father, we ask that you heal the emotional trauma and devastation she has experienced. We pray that you will restore her faith in love and relationships. We ask that you will help her to release herself from the expectations and control of her family, and to live her life according to your will.
We pray that you will guide her, Father, as she seeks a God-honoring relationship. We pray that you will bless her with a godly spouse, if it is your will, and that their marriage will be a testament to your love and faithfulness. We ask that you will help her to remain pure and to honor you in all her relationships.
We pray that you will give her the desires of her heart as she delights herself in you. We ask that you will guide her steps and make straight her paths. We pray that she will grow in relationship with Jesus Christ and that their relationship will be supreme.
In Jesus' name, we pray. Amen.
