It's hard to talk to him to begin with, I don't know how to do this
Most Helpful Girl
Well this is one of the toughest things a woman can do... but here is my take. Do it face to face. Be frank. Make it about you and not him. Keep it short. Move on. It will hurt there is no avoiding that but if you are honest and upfront it will help both of you move on quicker. He may even respect you after the dust settles.
