To break up with a man you need to do it face to face and in private. Be calm and firm. Know what you are going to say beforehand. Tell him that your feelings have changed due to no faults of his own. Let him know how much the time you have spent together has meant to you, but it’s time for you to move on. Don’t let them change your mind. Keep the exchange fairly short. Be kind, but sure of yourself, then leave.
