YES & NO.  Separation from her is causing you drift. In the day you are ok, but in your subconscience you are not ok with the long separation.  Since you have not acted on this dream, you have not committed the offense with your body, but you have already committed it with your mind.  You are only a MAN, it is very honourable, that you are faithfull.  You will have to castrate yourself if you don't get to see her soon. Your hormons are going nuts.
