If you felt at peace about breaking up with her that last time and felt that God led u to that decision you are probably correct. god is not the author of confusion, and if this situation is confusing you then you need to remove yourself from it. God will work out what needs to be worked out. In the meantime continue to pray, trust and lean in Him. Give yourself the time to hear God speak to your heart clearly and do not let your fear and anxiety (from losing this girl) allow you to make rash decisions. Pray each and every time you have the urge to reach out to her, wait and be patient. God will see you through.
