I have a question for anyone who has been around the block with love, really appreciate some advice?

I understand if you love someone you shouldn't hide things from them, but you need to understand that if he loved you he wouldn't have broken up with you. However mad he might have been at you the thought of loosing you should be more powerful than the fact that you hid something from him. Specially if it was the first time and it's not a reoccurring theme in your relationship, you talking to other boys behind his back, I mean. I think you for one need to leave him alone and for two when he does come crawling back (BECAUSE HE WILL) you need to set the record straight and tell him it is not okay for him to just walk away from you. In a relationship you both need to work together. It is not okay for him to just dump you for something so insignificant. He needs to grow up, and you need to move on.
