Dear Needs Help: It's hard when a relationship ends. Sometimes people just can't let go. You must be strong. Make it perfectly clear to your ex that the relationship is over. If you continue to hang around with him at school, he may feel that your relationship hasn't changed that much. If you've already explained how you feel, and he doesn't listen, state it again clearly. Tell him that he's making you feel uncomfortable. Don't let him continue to manipulate you. Eventually he'll begin to see that you mean what you say.
