In the dream it is showing how you and your ex will get back together. With you parting for a second is referring to this time in his life where he has found a new GF. There is no " time" when it comes to dreams. I believe this is a prophetic dream and will take place in your life in the future. If you are wanting to be with this man then you will have to be patient and keep faith knowing he will he will come back to you. The dream was given to you as to help you keep this faith. If you do so then your ex will indeed come back into your life.
If it was your anxiety, the dream would not be showing that he returns to you. Unless you have emotionally gotten over the feelings relating to him leaving you. Have you worked through these emotions? If so, then it could be symbolic of your feelings being restored. My first impression of the dream was it was prophetic.
Then it would not be prophetic with him coming back into your life but prophetic with you being able to move on. When you cried out to God he heard you and answered you with this dream. It would symbolic of your emotions being restored and your relationship with this man will be restored with a new relationship in the future at the right time with the right man. Dreams can sometimes be a little confusing, every little detail can change the whole meaning. I understand your dream better now that you have gave me a little more insight. Thank you. I hope this helps you in some way.
Your welcome. I can not tell you for sure what will truly happen other then what the dream is showing. It is either restoration with your feelings for this man, or he will indeed come back into your life. Time will only tell. If you keep having dreams about him coming back into your life, then it would be showing he will indeed come back into your life as I got from the first impression of your dream.
