God bless you. I know it is very hard especially without Jesus. Jesus says "if we love others more than Him, we have no need of Him". God gave you life. One of God's commandments says "love the Lord God with your whole heart, soul, and strength and love your neighbour as yourself." If you love yourself no matter what happens then life is worth living. God gave you life. He knew you before you were born, and He knows the number of hairs upon your head. God loves you and He wants you to love Him with all your heart, soul, and strength. You must love yourself before you can love another.
There are a lot of relationships that have been broken through betrayal. To move on, we must forgive the person and move on. It could be a blessing in disguise, and not rejection. God has warned us not to lean on the arms of flesh, for it will fail us. When some relationships are broken up, one might commit suicide, or become vengeful and cause death. Those relationships were not healthy and could be co-dependent. When we put Jesus in the center of our life, He shows and teaches us how to love and balance things in our life.
I prayed and forgave those who have betrayed me, lied on me, caused havoc in my home, even by loved ones. I had to make peace with God and myself by getting rid of my pain and turmoil within me. I had to have peace, and rest.
So ask Jesus to come into your heart, receive Him as your savior. He will help you to forgive this person. Father, I pray that even in her broken heart, that she will allow You to enter and abide with her. Father, draw her close to You, and wrap her spirit in Your love. Minister to her. Father, since we are separated from You, we look for love in the wrong places and in the wrong people, who too is looking for that love which is You. So Father, I pray that this young lady will give You a chance to experience the love of Jesus not just reading about it, but experiencing Your love. Tend to her in Jesus' Name.
