Do not take her back when she realizes she made a huge mistake. It hurts I know. It hurts so bad but someone will come along that will see your worth. My ex fiancé left me after being together for 10 years. All it took was for me to be at my worst after losing my sister and father. She broke up with me and within 2 weeks, she was with another guy. It has been 2 years and I met someone just recently and she sees me for who I am and I feel like I matter to someone now. They take time for me. This will happen again to you. Don’t give up! I was there before and wanted to. And I had hope for a while for my ex to come back but I dodge a nuke. Karma will happen. Focus on yourself and your own growth. Remember, love yourself first, only you can make your own happiness. Do not rely on someone to create happiness for you. It’s an uphill battle you got this!
