For a Leo, this month is a time for silence. To be a secret, and to stay away from people's prying eyes. In love affairs you might be shunned a bit. There could be betrayals, which is something you should prepare for, which is an actual possibility.
This month of June could also be a month of mystery. You may begin a forbidden love affair, not necessarily meaning adultery of course, but perhaps a love affair that was not possible before. Perhaps someone you have been secretly interested in, or someone who has been interested in you, will be revealed to you. Secrecy in the world of love is what governs you this month.
The month of June is also your astrological equivalent to 'whatever happens in Vegas, stays in Vegas." What does that mean? It means that if you have a secret desire, or some embarrassing passion, this month is the time to truly indulge this secret. This secret accomplishment will stay in the month of June. Whatever happens in June, will stay in June for a Leo, which should give you a strange sense of freedom.
