You say you have a boyfriend but showing that you are interested in someone else shows you are not ready for a committment. But that is okay too. You are young and don't settle for your boyfriend only to wonder what is on the other side or what could have been. Be honest and up front with your boyfriend. Tell him how you feel. I believe that if he loves or cares about you he will give you the space you need either to come back to him or go your separate ways. It reminds you of the old saying, "If you love something set it free. If it returns to you it was meant to be, it not it was never right to begin with. Maybe he is thinking the same. Could be a "time-out" to see others will get you in the right frame of mind to be ready to commit if it is your boyfriend, this other guy, or someone completely new.
Good Luck....
