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 commandment 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 happen then life is worth living" God gave you life. He kown you before you were born, and He knows the number of hair 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 relationship 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 warn us not to lean on the arms of flesh, for it will fail us. When some relationship are broken up, one might committ suicide, or become revengefull and cause death. Those relationship were not healthy and could be co-dependent. When we put Jesus in the center of our life, He shows and teach us how to love and balance things in our life.
I prayed and forgive those who have betrayed me, lied on me, caused havoc in my home, even by love 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 in your heart, receive Him as your savior. He will help you to forgive this man. Father I pray that even in her broken heart, that she will allow You to enter and abode with her. Father draw her close to You, and wrapp her spirit in Your love. Minister to her. Father since we are seperated 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 Jeus Name
