Be a representation of Christ and be loving instead of vengeful. 1corinthians 13:4-8 talks about how love is patient kind, not envious, boastful, proud, or rude, not self seeking or easily angered and keeps no record of wrongs, it is unfailing.... I understand you are hurt...but God has the right person for you ahead and being caught up on hurting the other person with your last words or trying to prove they are missing something does not do any good. Wait on The Lord and remember that Jesus said of all the commandments the most important two were love God with all your heart and love your neighbour as yourself. God said that if we don't have love then we have nothing.
