If you were dating or if she was your friend, decide if you still want her in your life. Either way, you might still be able to make her feel guilty, but it's best to figure out whether you still want her or not. Decide what she did wrong. Admit to any part you may have had in the conflict and focus on the specifics of what she did to offend you. Is she mean to everyone or is she only mean to you? Give yourself time to recover from the way she treated you. Stop talking to her. Avoid her at school, work, or wherever you normally see her. If you happen to run into her, walk past her and pretend she isn't even there. Focus on healing yourself without relying on time to do it for you. Surround yourself with friends that support you. Talk to your friends about how she hurt you. Give yourself a support group so you don't have to face her alone before you are ready. Before you confront her, make sure you have a clear idea of what you are going to say. If your thoughts toward her are very chaotic, take time to write down the specific things that are hurting you.
حدد إن كان يهمك أمرها أم لا. ابتعد عنها. فكر وحدد كيف قد جرحت هذه الفتاة مشاعرك. ضع خطة.
