What about this dream of yours? I just dreamed that you and your ex-husband made up.
Personally, I think this dream is just an idea of yours, and there is an idea in it. So personally, I think you made up with him in your dream. Are you happy? If so, it means that you really want to make up with her. If you really want to make up with him, then personally think you should take the initiative to send him a message or call him to chat, then you really want to make up with him, it depends on his attitude. If he doesn't want to make up with you, then you are very sad, right? If he is serious, then you two should make up.
So the above is a simple answer to your question. I hope I can help you and you can adopt it.
Then finally, I wish you health, happiness, good luck and all the best.
