How much damage does contact with the former do to the present?

If you can't get in touch with your ex, it will hurt you a lot, because her ex loves you very much and she will stay with you. He loves you with all his heart, and he thinks you belong to him alone. If you contact your ex, he will think that you don't love him and don't care about him. At this time, her heart was very sad. He may think that you want to leave him and love your ex wholeheartedly, so try not to have anything with your ex.
