I dreamed that my ex-husband was kind to you because your previous life was sweet, which played back in your mind, suggesting that you were looking forward to the happy and sweet feeling of your present life.
Dreaming of old love has nothing to do with ex-husband. It's that you have some vague concerns about your current feelings. Your ex-husband often appears in dreams. You should thank him and remind you to cherish the present relationship and stop having regrets and pains. I suggest you take a trip to relax for a while and increase your feelings.
