I voted YES.
Our resident dream expert interpreter Rook does not visit us very often lately, so there may be a considerable wait before you get any response from him.
But I would like to add my own ideas about what these dreams could mean, while you are still waiting for Rook's more detailed analysis.
If the guy never made an actual commitment to having a closed relationship with you, then technically at least he cannot be unfaithful to you.
Therefore both he and you are free to have a relationship with whoever you choose.
He has clearly chosen somebody else instead of you, and you are understandably feeling both disappointed and hurt.
Since you are also in effect a free agent, you could always choose and sleep with another man, but you would feel terribly guilty about doing it while you obviously still hold out the shrinking hope that the original guy will change his mind, and come back to you.
So your dreams are I believe a mixture of wishful thinking, unresolved and needless feelings of guilt on your part (although still very real) and your ongoing deep feelings for the man who has rejected you for another woman.
They (the dreams) show me that you are still holding onto the faint hope of him coming back to you, begging to be forgiven for ever leaving you in the first place.
I also think that you might be wondering if it was your fault that he chose someone else in preference to yourself.
But he cannot leave you if he was never committed to only being with you, in every sense of the meaning of the word committed.
I do not see these dreams as predicting anything. Either that they mean that he will change his mind, or that he will not.
But I do interpret these dreams to mean that you are currently unwilling/unable to accept the reality of your situation, and to let go of him with both your mind and heart. Which will if not faced with self honesty and courage hold you back indefinitely from moving forwards again with another man who does want to make the commitment to be in a loving relationship with you.
If the dreams are not enough by themselves to help you to once again be open to future relationships, you may eventually need to get professional help as well to dissolve your blockages.
If a dream theme keeps repeating itself endlessly and seems to be getting nowhere fast, professional help may be your only choice if you do not wish to remain single.
Nobody ever said that doing this will be easy,
